VERY HARD,,I DONT LIKE IT..

It's a cool looking puzzle, with a little extra difficulty over the 3x3, but when you take out the centers it really doesn't move nearly as well. It just doesn't move well enough to be a very fun solve. Maybe could lube it up and break it in better, but if I have to put all that effort in just to get it started being fun, it may just not be mechanically the best puzzle.

well I bought this exact same puzzle quite a long time ago in a random toy store for just 2.50 e. I still have it and overall quality of the cube is at the middle
but you cant expect much more for this price. the stickers are printed on the plastic but they hold on quite well. anyway in my opinion this is worth buying and its not a waste of money.
