Great fidget
Helps keep my problem solving sharp. Works as a great fidget. Arrived quickly. Very well built (I’ve accidentally dropped mine kinda hard a few times already)

Good, if deceptively easy puzzle.
Build quality is fine. Turning is a bit weird, but that's because until you figure it out, you'll commonly try to hold the puzzle on a part that wants to turn. You'll get used to it quickly! The only complaint I have is that it's a LOT easier than it seems; to look at the puzzle, it seems like it's absolutely crazy, but there's basic symmetries that show up that will make it very simple to figure out. I still don't know all the algorithms and can consistently solve it by just fiddling.

My kid LOVES it
Pretty cool and unique Rubik's cube variant, but much easier to solve. My kid can't yet solve a 2x2 Rubik's cube, but he can handle this one, and it is fun to spin the gears around

It moves and turns nice and smooth and have had no issues
This was bought for my 9 year old son who loves it. It moves and turns nice and smooth and have had no issues. My son and I have no idea how to solve it but it is just so cool in the way it moves that we dont care. great to try and solve or just watch as your kid trys because it's just so cool in the way it moves/

it's worth Way more than 5 stars.
this is a great puzzle, easy to solve but, still a great puzzle. it has a very nice feel to it. honestly, it's simply just fun to hold lol. I had it solved the day I got it but, that's ok because I know i'll end up solving it many more times in the future. I Highly recommend this puzzle to anyone who wants a new kind of puzzle, especially if you've never had a ball-shaped puzzle before. it is Definitely worth the money and it is an Authentic Mefferts & Oskar puzzle because the names are on all the centers.

Fun to have a second chance to solve a puzzle without cheating
While this puzzle is much easier to solve than a Rubik's Cube, you can't unlearn the Rubik's Cube and try and figure it out for yourself after you learned the solution from a friend, a book, or the Internet. The design ensures that edges and corners are either on the same side or opposite sides, rather than on any side of the toy, which reduces how far from solved this can get and affords solving with fewer, simpler algorithms. Still, having to devise your own algorithms and develop a strategy for stringing them together is a formidable challenge as the algorithms are completely different from Rubik's. Great fun.

Interesting puzzle. Kinda sloppy gears
Gears are kinda sloppy. That said, I'm probably just bitter because it was such a huge challenge for me. I can knock out a cube sub-2, but my brain just didn't grok this. My fault, not the toy's

Great cube or great ball persay hard when you first ...
Great cube or great ball persay hard when you first get into after a while I figured it out but after I made some algorithms and can solve it very fast almost never locks up due to its design it cetches about 1 in every 50 solves and all you need due is turn it back an inch to get it back to normal so I would really recommend this cube if you want something different and unique or if you want to try something a bit easier try the gear cube
