I have a guhong. It's a good cube but it pops a lot. I recently got a guhong II. Much better. Never pops, but slightly trickier to assemble since you have to assemble 5/6 of the core rather than the whole thing before you start. The last centre goes in last since it's impossible to get in all the edge pieces with it in place.
Please take off topic discussion off this forum. Thanks.
