It's a bizarre conundrum of a cube.
I'm going to start out by saying that this cube is polarizing. Not in a good or bad way, but it's extremely weird. ShengShou making a flagship? Weird. ShengShou making a cube with three separate magnet systems? Even weirder. And all that for $20 USD? I'm perplexed.
Unboxing is a pleasant experience. The box is nice, but there's a lot of foam in there (ever since MoYu boxes became super efficient, everything else seems wasteful) and it's a nice presentation. The accessories box comes with extra screws and springs, extra compression rings, and extra spring housing thingamabobs (they help with spring noise) and a very nice all-metal screwdriver. But that isn't why you buy the cube.
Let's start off with the features.
Dual-adjustment system similar to what MoYu uses, but no tool needed for compression. Standard spring, no maglev here
Corner-to-edge magnets
Corner-to-edge FEET magnets
Corner-to-core magnets
The design is a simple split-piece with primary tracks/feet for the edges and corners, respectively, and the center pieces are primary. On the edges, there is a bit of a strange jagged lip where the 2 body pieces meet, but it's not too big of an issue unless you look really closely. It only comes in stickerless, but the shades are nice and bright, comparable to QiYi shades, and it's so glossy that you could mistake it for UV coating.
Performance is decent. It doesn't cut everywhere, but the core magnet system makes it so that you don't need to corner cut very much even on difficult algs (for example, the Gc perm I use needs some weird finger tricks but they all work for me). It's very flexible and the springs are a tad weak, so I keep the cube on the highest compression setting. From the factory, it is a bit tight, so I recommend loosening the screws just a bit when coming out of the box.
Now for the feel. Oh boy. It's one of the strangest feeling cubes you will ever turn, and I guarantee it. A combination of the light springs, the feet magnets repelling at 45 degrees, the corner-core magnets being relatively strong, and the cube being decently fast means that it does not stabilize at all in between turns. It will either align or just not turn at all. The cube has a feel not unlike the GAN 12, where everything feels quite airy and the auto-align takes over a lot. The cube is a bit loud and has a low-pitched, hollow sound that sounds a bit cheap, but I personally enjoy it. It's light and airy, with very little friction, and has a slightly crunchy feel reminiscent of the newer GAN cubes, once again, but it's also not very tactile, like a Tornado V3. What is this thing?
Would I main it? No. But would other people main it? Absolutely. This is such a fun and wild cube that people who don't have GAN money but want GAN auto-align would be all over this thing. After a couple hundred solves, I got my normal times though they were ever-so-slightly inconsistent. I would absolutely recommend this thing for someone who wants to try something new.
