Using the booklet included with the product, it was pretty easy to take the knot apart, but difficult to put back together.

I ordered this for my son, who is young (7) but loves these kinds of things. Knowing he would need the assembly instructions I was happy to know they were included. He actually got it apart on his own!! But the problem now is there is a misprint on the assembly guide. Steps 9 and 10 are missing and 13 is printed twice. I hoped to find an online guide but I can't find one. I hope someone uploads one soon. Until then, I'm disappointed.

Finding a solution takes at least a couple of hours for an adult with some skills and experiences on brain teasers. Putting it back after dissembling is near to impossible without looking into the manual. You need to be observant and persistent to enjoy the toy.

It took me about 1.5 hours of continuously working on it to solve this puzzle, with zero help from a booklet or interwubs. I was in one of those moods where I wanted to be engrossed in a puzzle and this one surely fit the bill! It's difficult to put down once you start playing with it, but don't anticipate solving it unless you have some serious time on your hands. Reassembling it is also a major challenge, but I think I'm going to use the instructional video to do that. Then I'll attempt to solve it again and find out if I can do it any quicker the second time around :)

I thought this puzzle was going to be a real brain buster, but I worked out the puzzle in less than 2 hours. The product claims to have thousands of possible moves with only 65 correct moves, but it doesn't seem like there are that many ways to move the pieces once you get going. Simple trial an error will work out this puzzle rather quickly, and doesn't require as much thinking as I would have liked. However, it's durable and fun nonetheless.
