You can get them on cube4you or cubefans for 20 bucks its the Rubiks Speed Cube II I think. It has Rubiks color scheme and logo. But mine is too pop prone, Rama any way on how to fix this? I adjusted the tension as best I could, but if I tighten it it gets too slow. And the pops arent so common, just very explosive, like 3-5 pieces at a time.
