I got my trapdoor along with a mimic chest set a few days ago. The quality of both was pretty great. The trapdoor had what looks like a little bit of a bubble on the corner of the piece. Not a problem though. It doesn't effect the over all niceness of the miniature itself. I could have filled it in with a little glue but I left it as like a cracked tile kind of effect.
Other than 2D cardboard tiles, I haven't found many 3D trapdoor tiles, and certainly none with a nasty trapdoor mimic! The mimic itself comes in only three pieces, so is easy to assemble and paint.
Bought this piece for my Ancient Steel RPG game at a convention. Holy cats, the suprise on their faces when I replaced the trap door mini with the mimic was classic. Now I just need a few more mimics to make the players totally paranoid.
The quality of the mini I go was TOP NOTCH.
