I was super hyped for this cube, as we haven’t had a mass-produced ball core 7x7 yet. After doing around 25 solves, the frosted plastic is not breaking in at all, and the cube catches about as much as a 1980,s rubik’s brand 3x3. My best time on this isn’t even sub my official PR mean. This will NOT surpass the AoFu as my main and I do NOT recommend this at all no matter your skill level. If there was a 0 star option, this would get that.
