OOOOH! I own a lunhui 2011 as my backup. I'd love to see how this turns out! The 2017 edition ((I'll simply call them the Lunhui v2 and Zhanchi v2)) looks like the 2011 edition mostly. I'm not sure if it would have stats any better than the V1.
The 55mm Zhanchi was wonderful, a nice size and smoother than the 57mm.
56mm seems to be preferred for the top cubes now like Valk and GTS, but many others are still 57mm. I would say 57mm is still the standard, and the recent 56mm cubes are the exception, for now.
practically every speedcube released in the last year and a half has been either 55.5 or 56 even the budget ones and I while I reckon it is going towards 56 to be the norm now definitely not
I still think it could be a good cube, you never know. Maybe if you got stronger magnets then Damian got and had it tighter. Still will order it so I can tell the community what I think of it.
