Solarbandito and I conducted a fairly public transaction on this site. I thought it might be appropriate to report some feedback here. The puzzle (a Crystal Cube) appeared to be carefully assembled. All of the tiles are straight and secure. The mechanism has to be loose in order for the cubies to clear the tiles as it turns. I won't be doing any speed-cubing with it, but it is a very attractive puzzle. Shipping was very quick. Recommended!

what does it look like and how is it cut?

I can't describe it. Joel has a picture of a bunch of his puzzles here:

The crystal cube is the prominent one on the top toward the right hand side of the photo. It is a variant of a 3x3x3.

My six sided extended 3x3x3 and offset siamese that I got from Solarbandito arrive also very promptly and in excellent condition
