This will be a Xmas present, so it hasn't yet been used. It looks like it will be a hit.
It reminded him of the Rubik's cube, which he loved as a child.
I have a very smart nephew so instead of gifting him with plastic toys or junk, I try to get him gifts that will challenge his mind and creativity---yet still want them to appear to be a "toy" for his sake (I can't be the boring aunt always giving books!). This seemed perfect and boy was it! So fun, I almost kept it for myself and ordered him another one.

Great for anyone who likes special reasoning, (think stem people). However the design has two minor flaws: one hole gets in the way of the other two. This means the knobs have to touch, and I worry about the effects long term. The second flaw is that two of the sides not pictured are not clear as the other sides are. It's a minor flaw, but a little distracting and annoying when playing. Finally, it would be nice if there were given setups.
Fun and entertaining
Provided plenty of entertainment. Should be great for a mental pause while at work.
Very happy with puzzle...my grandson is still working on it. I live out of state so when I visit my grandchildren I always bring them a special treat
Very durable; easy to handle; open-ended progress. Easy to make as difficult or simple as desired. The colors are vibrant. The sound it makes--the clicks--are pleasant.
This was the perfect gift for my brother-in-law who is super smart, and really good at puzzles. He can make it super difficult for himself, or not as hard depending on the day, and he leaves it on his desk for quick brain releases. I love it!!!
