Review on Coogam Stickerless Puzzle Challenge Version: Enhance Your Puzzle Skills! by Blake Pudic

Probably the worst cube I've ever encountered, apart from the disastrous tiny Rubik's Cube. Out of the box it was very stiff and tight. Too much friction between the parts to turn well. The lube gave him a little boost, but not enough to save him. Corner cutting is non-existent and layers are often blocked. It's fine if you're new to cubing and not concerned about speed yet, or if you have very precise turns, but there are better options for the same price or less. I have some Quiyi Cubes that I like, but this one is useless.
