Today my "Skewb Curvy Rhombohedron" arrived. Unfortunately, it was not packed very well and three centres were loose in the package at arrival: the screws were stripped out off their sockets. I guess that some pressure during transport had caused the problem.
It was not a big deal to glue the pieces together. On the other hand, this should not happen and I'll try to persuade the selling company to use better packaging in the future.
Otherwise, this puzzle is really nice
I can confirm that "high quality" - as John Lin has stated in his post above - is the appropriate term for it. The stickers are fine, very shiny very well place. The plastic is solid and you get a very nice "look and feel" impression.
I clearly recommend it to everybody
who likes Jing's Pyraminx.
I like the clicking mechanism (some like it not so much, at least it is a bit less noisy than on the Jing's Pyraminx).
I consider solving it a bit harder than solving Jing's Pyraminx due to the confusing factor of a shape shifting puzzle.
