yeah - that was weird -it was really hard to turn at first, I might follow the other suggestions to disassemble and remove the blocking edges.

A good twist but the rotations block a little!!
I disassemble the cube and discovered that the edges have 4 feet instead of 2. These are small feet that block the rotations.
So I removed these little feet and the rotations become impeccable, there is no more blocking.

The frosted look is nice, but the top and bottom (non-fisher) layers grind against something inside the puzzle. unscrewing the top layer, I was able to find that there is a "torpedo"that catches on the corners. Sanding these down will help with the puzzle, although it should be carefully done.
