Based on photos, you might (I did) think this puzzle is about the size of a 2x2 cube (smaller than classic Rubic's cube). However it is almost the same size as classic Pyraminx, which is bigger than standard 3x3 cube! It turns like breeze right out-of-the-box! Some might think it turns too easy: turns do not "lock-into-place" like the original Pyraminx. The stickers are colorful and flawless.

It looks easy, and if you don't perform a shape-mod, it is easy to solve. But once you morph the shape (which is easy to do by accident) then it becomes quite a challenge! After you get it back into a pyramid shape, it will often be impossible to solve unless you morph the shape again.

A fun and surprising challenge! Recommended for any collection!

This is probably the best pyramorphix on the market. The turning is great, it barely ever locks up, and solves are fun.
Even though it is a bit bigger than you would think, the size is easy to get used to.
Overall, this is a must get for everyone.

Well I'm that not that into cubing but this puzzle was a great! The stickers are good as after weeks of messing around with no scratches or peeling or scratches. It moves very nice too! Would recommend.

While it was good while it lasted, the pyramorphix had some loose pieces that wouldn't stay on. Two of the corners kept falling off, and eventually, one of the internal pieces broke while I was messing with it, and I had to throw it away. I wasn't rough with it, so I guess it was just a bad batch. Amazing puzzle, not very well, built.

This puzzle grabs a little as I turn it.

This is a great 2x2 shape mod for any collector wanting to try something a little different, but not over the top. It is about the same size as a standard Pyraminx, which surprised me personally. Turning is exceptionally smooth and first impressions may lead you to thinking the tensions are a touch loose. Regardless popping or lockups are not an issue what so ever.

This puzzle is not a really easy thing to speed solve, but it is probably the most fun that i have ever had with a "cube" I love it and it is so cheap for the quality. ShengShou did an amazing job with this version of a pyramorphix. i didn't even really need to set up the cube as it was perfect out of the box.

The ShengShou Pyramorphix is a great puzzle. I still haven't figured out some of the moves, but it is pleasant to play with this cube. (Yes it is a cube in the shape of a tetrahedron.)

Although I bought this somewhere else, it is still the same. The puzzle turns very smoothly and is hard to wrap your head around. When I received it it was bigger than expected; it was as big as a pyraminx. However, this did not affect the puzzle itself, nor did it bother me. I actually got used to it - even grateful for the size - after a couple 100 solves. Yup, that's right, 100! I love this puzzle so much - I can just pick it up for fun and do a quick solve on it. The caps in the center can pop off, but you'll have to force apply a lot of force to get them off. It can barely corner cut - it wasn't expected to, anyways, since the corners themselves aren't curved. Fun solve, fun puzzle, good quality.

The shengshou pyramirpix is good right out if the box even though it's so greasy and it turns great espicially after lubing with weight 4 in the hardware and weight 1 on the pices
