The Z Concave 3x3 functions like a normal 3x3, but it appears to be pushed in on all sides, or "concave." It is currently available in stickerless only.

Our Promise to You
All of our products are guaranteed to be free of defects, or we will replace and reship at no cost to you. Please contact us within 4 weeks (28 days) past the delivery date to report any issues with items you have purchased.
Please note that some new cubes when being used for the first few times may experience what is termed a "pop". This is when one or more parts of a puzzle pop out without any damage actually being done to any of the pieces. This also occurs from time to time during normal usage. Pops are typically not considered a defect if the parts which come off can be reassembled by hand.
The corners on 2x2 puzzles should not be twisted as doing so may snap the piece. Damage caused by corner twisting is not considered to be a defect.

Should have read the reviews first. I've bought cube's at the dollar store that felt better built and turned just as clanky. First turn and it caught and twisted. Worst part is the pieces aren't even the same shades, the sides don't even match. Collectors item yes. Under the category 'worst purchases'. Wish I could post pictures of this eyesore.
that's all I have to stay.

This cube felt crunchy out of the box and didn't turn too well, but I lubed it and it turned better but still is kinda crunchy. I don't get why people say that this cube is bad, it doesn't pop, for me at least, but I haven't tensioned it but it is good, just not perfect!
I don't know why you're mad that this pips, it's slow, or whatever... This isn't a speed cube, it's a collector's item, please chill.
Don't buy this cube, it's completely useless. when you turn it you unscrew the screws, eventually making it fall apart. everything else is bad as well.
For the cheap price this cube is, alright. Out of the box it was very clicky, tight and extremely stiff, after tensioning is became much better but it does pop fairly frequently, I noticed it had some pretty prominent clicks on some of the faces and i realised that some of the edges were scraping against the core, I sanded down the mechanism and the excess plastic on the edges and it now turns much nicer. It is a good collector's item and feels really cool in the hands, but I would never think that of it as a speedcube, because of the popping issues and the lack of reverse corner cutting.
Interesting cube, and great collectors item, but pops like hell, even if you turn it slowly. Turning is decent, and I spose for $7 it is worth it.
I got this puzzle for my birthday, and it is very cool. It is notably squished in, which is awesome. The things I do not like about it is that, I have not changed the tensions and am too scared to, and the fact that some pieces came with dented scratches, if that makes sense. I don't care that it has its flaws, I mean its not a speedcube, highly recommend for messing around!!
When I took it out of the box it seemed pretty nice until I saw the blue side. It had two big dents int it and the blue red edge piece had a huge crack in it. I am pretty sure that doesnt happen a lot, and other than than a really neat cube with okay turning.
