This is probably the best 4x4 on the market and it is slightly smaller than most 4x4x4s at 59mm making it perfect for cubers with smaller hands and it is a fast and smooth puzzle that will be an aid to any speedcuber wanting to improve their 4x4 times. It is slightly better than its bigger counterpart but if you have large hands, this is not for you.
