I bought one for my 3-yr old son for a Halloween party and six months later it is still in one piece even though it is used almost daily by him and now my 1-yr old.  I had to wash it and it survived.  For 5 bucks definitely worth it - I just bought a second one for a friend (I think I paid about 3 for the first one).  My son has a BIG head (like an avg 5 year old) and it fits him just fine.
