I'm having problems with my Ghost Hand 5x5x5: can't find the "sweet spot" of the tensions.
In fact, my biggest problem is one of the sides, which have some kind of bump feeling. It's hard to explain, but no matter how loose this side is, it keeps locking and locking.
I even tried to loose to a point that the center cap is hard to get in.
(by the way, I ordered a V-cube 5, but having a defective cube at home just feels wrong)
It's the same size as the Eastsheen 2x2 http://www.cubesmith.com/Eastsheen%202x2.htm, but the stickers are pretty decent and colour neutrality is trivial on a 2x2, so no need to rush.
After following the guhong mod on YouTube, my corner cutting on the guhong has gone worse. The reverse corner cutting is amazing, but normal, its so so bad.
