Taking off the center caps to lube the springs isn't as easy as with normal cubes, but I was able to pry the caps off with a sticker remover blade. It is a little tricky to hold the cube, align the layers, and turn the layers correctly. It's also too easy to accidentally turn a layer that you didn't mean to. Just like the Qiyi Icy Amber Windmill Cube, this cube would definitely benefit from magnets, but it's still fun as a puzzle.
