My 5x5x5 was checkered, but I will count that as solved.
All of mine are solved, but I do need to repair my megaminx. It still works, but you have to be careful with the light grey side because if your not, the whole side will fall of. The center piece broke.
5 3x3x3s that are sitting on my desk. This is because when I am practicing new algs and I try them by memory, if I mess up I pick up another cube so I can try it right away instead of solving the cube to try the alg again.
