READ before judging. Honestly, I actually like this more than the AoFu WRm and the Meilong 7M.
.
It's pretty much the same size as the AoFu, and you can barely feel the core magnets, BUT this cube feels much more solid and blockier than the AoFu.
.
I heard some people reviewing this say its similar to the Hong, but describing how this cube came out of the box, it had some lube already in it, and a bit on the outside. It was also really tight, which I didn't like at first because I was so used to the AoFu, but after some silicone lubes and some DNM, this cube is still not faster, but it moves at a pace where you can solve fast, and stays in shape which may or may not have to do with the corner-to-core magnets (very controllable).
.
Unlike the Hong, which I found the inner layers to be so sluggish, the inner layer(s) on this cube actually feels extremely consistent on all layers, with both inners just being barely slower.
.
Regarding popping, honestly, the Spark v1 no matter what people said about it, I always found that it pops due to its second-outer layer's wing design, which is small and does not hook to any of the layer on the outside which catches, and pops which is very annoying unlike the AoFu. This cube however, the v2, has the same wing design as the v1, but somehow, (I'm not an engineer so I am not 100% sure), the wing ratio to pieces seem somewhat larger, and it hardly ever catches on the outer layers, which I found extremely good and I hardly ever popped. In fact, I popped on this cube less than the AoFu somehow, though I still think the wing design on the AoFu makes more sense.
.
Texture - Unlike the v1, this cube does NOT have primary internals just as the pictures. It starts out with the classic QiYi sandiness, but after lubing, it still feels cohesive, but not as sandy. Holding the cube, it has NO UV coating, but rather the normal QiYi semigloss feel. I didn't like it at first, but now I kinda do.
.
It all comes down to personal preference, but if you prefer cubes that are more stable and controllable, this is THE 7x7 for you.

It's literally the Spark from 2019. It's just smaller and weights less. Garbage.

It is good 3x3 stage is stable, the layers are easy to turn. The screw shakes a little you can test it moving the center layer with no caps to see it. It is really dry out of the box.
