Does anyone own this puzzle? Is it any good? Quality? Thanks.

yes, i have one. i was not that impressed with it.
the puzzle pieces are okay quality but the cube you are meant to stick them to is just made of cardboard (if i remember correctly) so you could easily squash it trying to push a piece into place.
on my one, there were a few places where the pieces were a tight fit and would sometimes pop out and fall off.

it is in a cupboard somewhere and i will get it out when i get home from work tonight and have a fresh look at it.

I bought one for $3 and feel that I got ripped off.

One thing to note is that the colors are all wrong and could not exist on a real Rubik's Cube the way there are here. There are 2 red and 2 green centers and a corner with 2 yellow sides for example. Considering this is an official Rubik's product I was really disappointed.
