So a few days ago I got a delivery from theCubicle.us containing 3 items - a tube of cube lube, a Yuxin 4x4 and a Shengshou pyraminx. Today, I am going to be reviewing the Shengshou pyraminx (can be bought here). First of all, a pyraminx is a four sided pyramidal puzzle simmilar to a 2x2 in difficulty. This is what a pyraminx looks like:
It had two ways of moving per axis, the tips and the main segment. This can be seen in the next picture:
Here you can see the base layer, the middle turned layer and the tip. The center pieces (the blue pieces) can be seen here:
The centers, unlike a 3x3 or other odd numbered cube, have three showing faces, and can rotate so are not always the same. Although the pieces may rotate, they cannot actually move relative to the other faces of that piece as they are fixed to the core. The pieces between two centre pieces are the moving pieces like edges on a 3x3, and are what you have to solve.
Onto the review. The puzzle turns extremely fast, only partially hindered by the ball bearings to keep the layers in place. This problem is not relevant, as you would never need to turn a pyraminx more than one as it has only three possible places to turn to. The ball bearings in the sides of the pieces add speed to the turning as well as lock the pieces into place so that you don't have to be as accurate with turning. For a size comparison, here is a picture of the pyraminx next to a standard 55mm ZhanChi:
One piece on the pyraminx is the size of one and a half pieces on the ZhanChi. The corner-cutting is a third of a piece and no inverted, but this is not needed due to the ball bearings. Locks and pops are both non-existent, as the puzzle turns very well. I have brought my average down to 20s and my PB is 12s
I would greatly recommend this cube to anyone with a previous puzzle knowledge, as a pyraminx is not the best puzzle to start with. This puzzle is extremely cheap at only ~£8 (~$12) at theCubicle.us and is definitel worth it.
