A few review suggest that it explodes. I say 'You used too much force!'

The cube is a bit more delicate then the three other cube by Rubik, but it has held up pretty well, and I do use it quite a bit.

I am now solving this cube at least once a week (to avoid memory loss ^_^). It also build determination as it will take around 20 minutes.

Once you are able to solve the Professor, all the other cubes seems too simple.

This is probably my favorite Rubiks puzzle. It hasn't fallen apart on me yet, and after several weeks of wear and tear turns quite smoothly. Solving the center pieces is pretty easy, and matching the edge pieces is fun to do; never quite the same combinations. And then you get to finish by solving it like the 3x3x3.

The Rubiks Cube and the Rubics Revenge are both relatively difficult. The Rubiks Professor adds another level of difficulty compared to the other two. Like all Rubiks Cubes, they are made to last a long time and can take quite a beating. I recommend this if you are able to complete the Rubiks Revenge.

its a great game i also bought the revenge and of course the rubiks classic cube. i like solving it over and over just for the fun of it.

I bought this for my daughter. She has already mastered the three by three and four by four Rubik's cubes. This was the natural next step. It is exactly what we expected. And she is close to figuring this one out, too.

They should have invested more on the manufacturing, since a couple sticks were not exactly in place. Anyways, I do recommend.

This is alot of fun, easier than the 4x4 i think. Its really fragile and the inside corners pop out. I super glued one back together and it has stayed. I heard that the other manufacturers make more durable ones.

My son plays with this constantly. several of his friends are into rubik's cubes. they even use a timer to challenge their completion time. so far very durable. they use the internet to find the algorythms to solve it.

I've become obsessed with rubik's cubes lately. After becoming bored with both the 3x3x3 and the 4x4x4 I was looking for a challenge. I bought this cube despite the many reviews saying that it is fragile. Right out of the package, several stickers were already falling off. I had to glue them back on. After two weeks Ive already had to glue on a couple more stickers. To the cubes credit though, I had been using it very heavily, solving it several times a day.

It is fun. It's not really as hard as it looks however. If you can solve the 4x4x4, you can solve this. it just takes a little more thinking. Right out of the box, with no instructions it took me about an hour.

Occasionally, when Im really going at it, one of the inside pieces will get in a bind and appear as if its going to break. I still havent actually broken it though, and Ive really put it through the paces.

My cube turns really well and requires no luberication. Rubik's cubes tend to vary on that though, some cubes turn amazingly while others barely turn without any lubrication.

In my opinion, if you really like cubes and want something more challenging, you will like this. As long as your careful and dont get in a hurry while solving it, it should stay together.

When I first got the cube, it had multiple sets of pieces that were welded together. After spending over an hour filing away the space with a safety pin, and moving it around for a while it worked perfectly. I hope this incident was a rare occasion and not a common occurence, but it was pretty lame, especially for a $30 rubik's cube.....

I got the product within a good amount of time, the only problem was the condition of the box when it arrived to my house.

I don't know who Amazon uses for their shipping but they might want a better quality control system or something. The box, when I found it, showed evidence of being smashed. The corners were all indented and one of the sides looked like an accordian. The top of the box was halfway open and the tape was barely holding down the other side. The box, which was laying on its side on my doorstep could easily be seen into. If I had ordered something that could be considered even slightly "fragile" it would have no doubt been broken.

Though the product I ordered was unharmed, I would like to see a change made in the shipping procedures.

This was the first time I have ordered something from Amazon and I would have to say that I was less than impressed.

I did order a 4x4x4 Rubik's Revenge Cube here and when I got the cube, it was stiff and hard to rotate. This new 5x5x5 was barely stiff and didn't require much lubrication. I use Silicone to lube the inside of the cube.

The cube is fragile like most cubes bigger than the standard 3x3x3. Though this cube moves very well and is built very well. My only concern is the 8 center pieces on each side. The very center piece of just fine but the pieces surrounding it are quite loose but are at least staying on.

People have actually complained about the cube being heavy, the pieces pop right off the cube a lot and the stickers peel too much.
The cube is heavier than a 3x3x3 and 4x4x4 but honestly, if you can't handle the weight of the cube you are just skin and bones. The pieces will pop right off if you try to speedcube with it or not take care of it; the commonsense stuff. Finally, the stickers will peel off eventually, but will peel immediately if you treat it poorly; scratching it, sliding it across a desk, storing it some place where it can be scratched or crushed.

Overall, the cube's construction is very well done and is not that challenging because I can solve a 3x3x3 and 4x4x4 without any trouble. This is a good brand, Eastsheen (a rival brand) cubes are garbage and this is the brand you should go with.

I got my 5x5 rubik's cube recently and it is very fun. I am a previous solver of a 2x2, 3x3, and 4x4 and the 5x5 is giving me a great challenge. However, I have already solved it but it takes me awhile. I can solve my 2x2 in less than 25 seconds, my 3x3 in less than a minute, and my 4x4 in about 2 minutes. This cube is great for me and i think and rubik's freak should consider this product. WARNING: Pieces may break off easily. Be careful with this cube for the first week or two to prevent explosion.

I bought this for a friend and haven't given it to him yet so I wasn't very sure about how to rate this toy, but I did open it to add a note inside so I've played with it a little, but not too much because I was afraid I'd scramble the boxes and won't be able to fix it. But when I handled the toy, it felt pretty fragile but I don't think it would have fallen apart after a couple of days of play. It would probably break if it fell from the hands of someone though. I guess my friend would just have to be careful. This toy looks pretty challenging and fun though.

Everything was just the way is supposed to be.....

no problems with anything

thanks

This is a must buy if you have already finished the 3x3 and 4x4 cubes. You will need move sequences from both to solve the 5x5 (as well as some completely new sequences). The stickers are terrible and will start coming off within a few days. I simply took them all off and painted it myself, which lasts longer anyways. Also, DO NOT TURN FAST, because when i started getting the hang of it, one of the nine center pieces popped right off and its unrepairable. The cube is still usable, but there will always be one piece missing.

I bought this 5x5 Rubik's cube for my brother for Christmas. He has solved the 3x3 and 4x4 before, so he was really excited to get this one. He had it solved before everyone had even finished unwrapping the rest of the Christmas presents (but only because he has mastered both the 3x3 and 4x4). It has the more durable stickers that don't fall off and lose their color if you use the cube a lot, which is a plus. However, it doesn't turn as well as the 3x3 because it has more parts, so it can't really be used for speed solving. Definitely a good buy if you enjoy the 3x3 and 4x4.

I purchased the Rubik's Professor Cube 5x5 for my 16 year old son for Christmas. He had already solved the original Rubik's cube several times and was working on the 4x4 cube. When he opened this, he was amazed at it's massive size (as compared to the 3x3 cube) and was ready for the challenge. He solved the 5x5 cube 5 days after he opened it. He loves it!

I am a Rubik's Cube lover and bought this 5x5x5 one recently. The mechanism is very well built, but the stickers are absolutely terrible. In less than a week they start to fade and peel. I had to replace them all. So, how can a product be sold with such deficiency? I hope Rubik's start selling these cubes already with the PVC stickers they have.

The order took a whole month just to ship and there wasnt any holidays during this time period either the item was great but the delivery speed was terrible

after id played the 4x4x4 cube for awhile,
the inner pieces tended to pop out.
i was afraid that this would be the case with the professor, as well..
but that hasnt happened at all.
and i spin this cube at least 12 times a day.
the pieces still have a firm hold and spin well.
the stickers began to peel within a few days,
but i am hard on stickers, so it could just be me.
=P

all in all..
im gonna give this cube five big stars.
its one of my fav toys ive gotten from amazon.
(note to amazon: get the 6x6x6)
=]

Reading other reviews I noticed that people are not pleased with the durability of the Professor Cube. However, in the package it states that is NOT for speedcubing. Maybe is a little pricey, but that only makes me take more care of it. Durability if just fine.

The stickers are another story. After a few weeks of constant usage, they start to peel off their transparent cover and the colors begin to fade. Just make sure you are gentle with the cube and you'll enjoy plenty of hours of fun.

This puzzle is a great challenge. There are so many more pieces to put together, and the smaller cubies feel great in the hand. However, the cube is inherently fragile, due to the much much greater number of moving parts (all held together by each other, buy the way). If you are careful of this cube and buy it from a place you know has a good return policy, it shouldn't be a problem, but it is easy to misalign it by accident and have a piece twist out of its spot...

I don't solve competitively, but I do spin the sides around pretty fast when solving. The durability is really dependent on the tension of your cube, which unfortunately varies a lot and isn't adjustable in this cube. I had a cube before the one I am reviewing, and in 4 days it popped and I returned it. The one I have now is nearly perfect tension, and it turns well and hasn't popped yet.

The stickers peel easily, and that is the main flaw of this puzzle. Fortunately there are sites that sell great quality stickers for cheap, but the cube really should include great stickers stock, the ones it comes with peel within the first solve.

And, of course, its a rubiks cube design, so its fun and educational.

I recommend it!

The cube is very fun and cool, but the colored stickers started falling off after a few days. In my opinion, it was still worth it. I will not purchase replacement stickers because they won't stay on. I just used colored permanent markers on the squares missing stickers.

About 2 months ago I bought a 3X3 and decided to solve it. The first time, it took me about one hour to solve. In three weeks I was down to just under one mineut, not fast by some standards, but it was fun. I then turned to the 4X4 cube. This one was a little more of a challange. It took me about 4 hours to solve this one for the first time. Finally I moved on to the 5X5. This one took me one hour to solve the first time and I am now down to about 5 mineuts to solve (mostly because you are not able to turn it very fast without tearing it up.) This one is no harder than the 3X3. In fact if you can solve a 3X3, you can sove this cube with the same algorithms joint with simple intuition. Overall very much fun. And a great way to waist a couple mineuts if your bored of the spherical nature of everything around you.

If you've mastered the 3x3x3 Rubik's Cube and the 4x4x4 Rubik's Revenge then the 5x5x5 is the toy for you.

It provides that extra challenge, but you can use

strategies from the smaller cubes too.



My only disappointment is that it did not seem quite as

robust as my smaller cubes which I have had for

over 20 years. Also a couple of the colors are already

showing some signs of peeling at the edges - whereas my 20 yr old cubes look as good as new.

I have no idea what the other reviewers that claim their cubes were so durable were doing, but the inner squares on my cube pop off no matter how much care I take with the cube. The piece has a very thin, delicate neck and breaks very easily. Also, the stickers were wearing off within two weeks of using the cube. I contacted the company on the box and they were kind enough to send me a replacement... which the stickers wore off after two weeks of use and the inner squares broke no matter how much care I took. I have found replacement stickers on the Rubik's website so I've been able to solve the falling-off-stickers problem. I've rated this toy as 5 stars on fun because, even though it is very frustrating when the squares break, it's been kind of a new puzzle taking it apart and supergluing the pieces back together every time they break (think 'model-building'). I've been able to play that game well over 20 times so far between the two cubes I have now (the one I bought and the replacement cube). I just recently took the two cubes apart and made one good cube with the unbroken inner corners. We'll see how long this one lasts.

I don't know why I didn't buy one of these sooner. Just to look at it through the packaging is worth any reasonable full price. The process of solving it is a combination of solving the 3x3x3 and the 4x4x4 cubes, though I haven't actually solved it yet; there's a little more to it than that. There are a few websites out there that supposedly step you through the solution of the Rubik's 5x5x5 "Professor's" Cube, but understanding and interpreting the written instructions seems to take as much skill as figuring it out by yourself.

The thing that disappoints me most about this particular cube is how easily certain stickers start to peel off. I had to go out and buy some super glue to stick the peeling corners of the top layers of the stickers back down. It's not the kind of thing you want to get up and do less than a day after you've started playing with this very cool toy.

This is a great puzzle for anyone over the age of ten. Anyone younger would probably get frustrated with it too easily. Overall it very fun to solve, even if it does get mundane after you figure out the technique. It obviously takes more time to solve than the classic 3x3 cube, as well as the 4x4 cube, but once you know how, it definitely isn't any harder than either of them. The cube comes very stiff (hard to turn) from the factory, but after you play with it a while it tends to loosen up. The only gripe I have is about how easy it can be to "lock" the slices by not having them lined up right, but once you get used to it, you have the problem less and less. Suggested for anyone who enjoys a good challenge!

I bought this puzzle for my kid after he solved the original cube. I had read the review here and other places stating that one needed to be cautious when turning the puzzle. However, our major problem with it was that the orange stickers (within ten minutes of playing with the cube) began to peel back and fall off. We tried using glue (they had no stick to them) to put them back but it was not long after that the green stickers began curling back and falling off as well.

The major problem is that these turned out not to be "stickers" after all, but rather colored squares of vinyl adhereing to additional stickers beneath (all white) by means of static. They fall off easily.

This is a nice puzzle for show (impressive on the desk) but not for actual continued use. Hopefully, Rubik's can use proper stickers or adhesive in the future and maybe even tighten up the design so that this can be used as a fun puzzle.

I'm an avid Rubik's cube player of the 3x3 model and have owned my cube for nearly two decades. Since I can solve it in under 2 minutes, I decided to invest in the 5x5 for a bigger challenge.

Unlike its robust sister (my 3x3 cube is well lubed with vaseline, and only has one re-glued sticker), the 5x5 proved fragile within the first two days. I used a careful touch, since I'm very familiar with how untried cubes explode. Nevertheless, many stickers started to peel on the first day, and two of the center squares have completely falling off and look to be non-reparable.

I lubed my 5x5 before using it, though it's more difficult because the squares are smaller and turns tighter. I was also careful to turn rows precisely to avoid misalignment and subsequent explosion. Even so, it broke on me. It's a shame, because I was really getting into the challenge of it. Now, it just sits like a broken toy on my desk.

For a $30 or so product, I find this inexcusable. Rubik's is supposed to have a strong brand name and I have been very happy with my 3x3 cube. I'll never invest in another Rubik's product.

Pretty cool, but I'm only giving it 3 stars because it is SO hard to move. It took me 5 hours to solve and I guarantee most of that time was trying to move it! It also sometimes feels like it is going to fall apart. However, still an awesome product.

I bought this 5x5 for my fiance. He was a bit frustrated since he wanted 3x3. Well you will definately find 5x5 more difficult and I guess my fiance didn't like such a challenge. However it's a good challenge and he'll try to solve it after I get a 3x3 one first. :) He found 5x5 very fragile. You just have to get used to it. Otherwise, it's a nice thing to have and entertain your guests. :)

Just to add to what others have said--the orange and green stickers are falling off my cube after about 3 days of use. When the color peels off, it leaves a white box underneath, which I guess I'll color in with a permanent marker or something.

No regrets on the purchase, but the shoddy construction is annoying.

I had heard rumors of this cube, and didn't find it until a few months ago. It is, quite obviously, much harder than the 3x3x3, but it's fun to twist it, especially to see the combinations of colors impossible with smaller cubes. And no, I haven't solved it...yet(Bum-ba-ba-bum-ba!)

You do have to be careful twisting it. But it does warn you on the box that it's not for "speed cubing" or the like. Also, they do not include a hints/solution manual, but do give a website. I haven't broken it yet, and unless you're just reckless or impatient, it would be hard to do. Overall, it's a fun puzzle. I would suggest buying it only if you like the original cube, but that's just me. It's fun on its own merit, too. That's it for me - long live Rubik's Cubes!
