I bought this cube a year ago. This cube is very stiff and slow to turn. It often requires several tries to get a layer to turn. I loosened the screws and it turned much better, but the center pieces fell out frequently. So... I eventually just tightened it back up so that it did not fall apart and I just have to deal with the stiffness. However, it seems to be the only 4x4x6 available, so I am glad to have it in my collection. This puzzle is fun and pretty easy after about 20 solves. I highly recommend the crazybad 4x4x6 fisher cube over this cube. the crazybad is wayyyyy more difficult, wayyyy higher quality, turns awesome and smooth, never pops or locks up, and remains challenging after hundreds of solves, and has several challenging PLL & OLL parity issues.

This is a fantastic puzzle. In my experience with it, it has been incredibly stable with no pops or locking up to speak of. Sticker quality is pretty darn high and I doubt I could have stickered it better myself. In terms of challenge, it's pretty high up there. If you're familiar with lower order cuboids you'll be fine, but shape-shifting and parity/placement issues are in full swing here. The puzzle tends to resist you slightly when turning due to the large size and friction cause by the increased number of individual pieces. I have relatively large hands so it isn't an issue for me, but for younger puzzlers or those with smaller hands the puzzle will benefit greatly with a tiny shot of your favorite lubricant. That is my only real gripe with the puzzle, and it's barely a gripe at all. Definitely worth the cost.

Coolest massed produced cuboid
This is hands down the coolest mass produced cuboid out there. It shape-shifts, which is a really nice addition when you're presenting it. Its quality is really nice in both the cube itself and the stickers. over time, the Calvin's Puzzle logo does wear off, but the TomZ logo stays on. The only issue that comes with this cube is popping. On tighter tensions, it's less likely to pop, but when it does, it's a pain to put back together. Though, if you're experienced enough to solve one, putting it back together isn't too hard. If you can overlook that, then I'd definitely recommend getting it.
