Overall I like that it's stickerless and easy to turn. If you're like me though, I usually try to time myself for speed and in doing so on my other cubes...I'm able to spin one side while starting to spin the next side before completing. Not so much on this cube. Since this is a 7x7, the squares are small and if you spin one side without completing the turn and then starting the next, you'll jam the cube. I did this on the 1st day and one of the inner squares popped out. I thought the entire cube was going to fall apart but I was able to turn the square where it popped out and somehow was able to snap it back in. I jammed it once more after that but a lil shaking and it unjammed itself. I guess don't use this cube for speed timing and just take your time with the turns and you'll be fine.
