One thing I noticed at the world championships was that all these really fast chinese kids were still using ordinary sized Gan cubes despite their hands inevitably being way smaller than most other top cubers. Gan did release a mini version of the Gan 11 M Pro so I was curious as to why they were not using that instead. I wanted to get Yiheng Wang, who currently holds the 3x3x3 average world record, to solve the DianSheng 10CM 3x3x3 and he clearly stuggled to solve it quickly.
