My son is a Mike the Knight fan and needed a helmet, so I ordered this one.  He loves it.  It fits perfectly - he is 3 and a half, with an average head size.  He seems to be wearing the visor like a chin strap, which looks pretty cool and seems to be the way he thinks it should go.  He wears it a lot and is rough with it and it's still holding up after a few months, so I think that's great.  Only thing he didn't like was the lack of a feather on top, so we went to Michaels and bought a feather and duck taped it to the top, and he's happy with that.  My only complaint is that the helmet has a slightly smushed look (since we got it).  He doesn't care and it's not that noticeable, but it's the reason I gave it 4 stars instead of 5.  Still, I think it's a great costume piece for a great price.
