The concept is great, the execution is piss poor. BUT- the masks are around $25 so that is what I would expect. I used a few the year before last (after a make over) and they lasted the season but did not function well by the end (werewolf models) the foam on the side of the mouth (the skin is foam) tore almost immediately. I ordered three this year to alter into Yeti masks (night fiend) and I plan on replacing the foam with silicone. The finish on them has taken a major down grade since last year- they seem cheaper to me.
They are ~$25 so for that price they are acceptable.
That is my assessment,
