Good grip, is just the size of the palm of my hand. It runs fine (without going too fast either if all is well aligned). It seemed difficult to appearance, but for my part, I find it easier than the 4x4x4 and 5x5x5 that I also own. I still put 1:20 to finish it by quietly so it occupies a good time. I recommend it to those who like the Rubik's cube long and not too complicated.
