Well, I've been cutting my own hair for around 12 years now.
Now, I don't do any kind of fancy hairstyles, but rather whats called a "Burr cut".
Yeah, so what about all the add-ons that came with this package...???, well I won't be using them, but the clipper did came with its hard-on carrying case and the model was the cheapest wahl that came with a taper control for a much clean cut.
The blue thingy does make it more comfortable when cutting your hair.

I've purchased this product twice, thinking I just got a bad set on the first purchase. Nope, both are crap.

When you use them out of the box, they simply don't cut hair well. They pull and tug and rip out hair.. and barely at that. They bind up with just the tiniest bunch of hair (my hair is very short (less than 1/8") and thin, so it's not like I'm overloading the clippers.

I noticed that the front set of teeth did not appear to be vibrating back and forth; they seemed to be mostly holding still. I've tried changing the position of the little control wheel that you can turn with a screwdriver, and this helps a little but then the things growl so loud you can't stand to have them by your ears.

I tried slightly loosening the "fixed" set of teeth (I know there's a more technical term.. maybe they're just called 'blades'?) thinking that the front set was pressed too tightly on the back set and that's why the front wouldn't vibrate and cut. That seemed to help a bit but then soon after the vibration causes the back teeth plate to become very loose and then then the clippers won't cut again.

10 years back I owned some clippers from Oster, I believe, and they were beautiful. Worked perfectly, smoothly, quietly, right out of the box; just like you would expect.

I wouldn't have another Wahl product if you paid me.

I use this monthly. Doesn't cut as close as some others, but works just fine and it's a good price.

It is a bad product that I can not even used on the first time to cut hair.

Ok, so the Wahl brand is a good one in my mind, so I thought for sure I was safe purchasing this haircut kit even though it was the cheapest I could find on Amazon. Well, apparently Wahl makes cheap China quality stuff too.

I first opened the thing up and tried to give myself a haircut one night around 11:30 PM. Sure enough everything I needed was in there, full selection of guards and trimmer attachments etc. It also came with full color directions on how to cut your own hair which was nice. Great. I prepared to let some hair fly.

I have thick hair to begin with, but I figured I'd start a little longer than I usually need and then trim down from there. I started with a No. 5 trimmer attachment. Well, long - VERY long - story short, I didn't actually finish the haircut until well after 1 AM. Granted, I'm more of a hair-cutting novice than anybody, but the fact is these here clippers are as weak as snot. They jammed literally every 3 seconds of cutting. Oh, and I ended up with a No. 7 length haircut simply because it would NOT cut my hair with the No. 5.

About halfway through I realized that there had to be something wrong and I scoured the owners manual for a troubleshooting guide. It said you can actually turn up the clipper's power with the adjustment screw on the side. So, after ruining the little plastic screwdriver they sent in the kit to no avail, I got a real screwdriver and adjusted the power. Ok, it was a lot better (I could actually CUT the hair), but it still jammed probably every 15 seconds. I would stop, knock out the little remnants of hair in the clippers, sometimes take the plate off, blow on it, put it back together and most of the time it worked. Sometimes it didn't and I would have to insert various heated insults into the process.

The kit was cheap enough that it would be too much trouble to send back so here's a lesson for me: cut your hair once a week so it only needs the faintest of trims. Lesson for you: don't buy this if you have thick hair. If your hair is wispy thin you probably won't have a problem, but otherwise steer clear and get something with a little more quality.
