Bought for my 4 1/2 yr old grandson along with "BumbleBee" costume so that when he is BumbleBee, his friend can be Optimus Prime.  The plastic mask that comes with costume is not great but what you would expect for the cost of the costume.  I had also purchased the the Optimus Prime and BumbleBee Voice Changer Helmet so I didn't care about the mask.  I felt costume was priced right and quality was relative.  My grandson loved it!
