My 5 year old daughter loves this hat.  It is just a little loose, but is not a problem.  The lights work and flash different colors and are really bright.  They can be turned on and off  thank goodness,  My only beef is that the string that holds the hat on, does not have a sliding fastener to adjust the size of the string...you have to tie it.  But for the price, what do you expect I guess.  It is a nice fun hat for a 5 year old and the quality seems fine
