I got this for my boyfriend as a gift and he loves it. Instead of being stuck with the same thing over and over, he can change his hat on a whim. It hooks up to his phone pretty easily and can change to all kinds of patterns and designs. I didn't realize when I got it that it would work as good as it does, but it does. Since normal hats are this price having an LED screen makes this one even better. Its like having 10 hates... or more for the price of 1 really.
Be careful when going out in the rain or cleaning this hat since... duh... its electronic.
