the magic skewb from shengshou.
For its size, quite a heavy cube with a klicking feeling. The plastic feels solid and the stickers are clear. Skewb's turnaround is very nice and easy to control. Because of a special mechanism, when you turn the puzzle, it will click into place. This is particularly useful in speedsolving. It has superior quality in plastic and when it comes to stability. The puzzle has a slight clicking sound, because of ball bearings on the internal mechanism.
