Review on USB Rechargeable LED Beanie Hat: Hands-Free Headlamp Cap with 4 LEDs for Unisex, Ideal Winter Knitted Night Lighted Hat Flashlight - Perfect Gifts for Dad, Husband, Him & Her by Matthew Sutton

We have now bought 3 of these hats. I bought one for my husband. This man sweats so much but is obsessed with flashlights which is why I got it for that reason alone. But he absolutely loves it and takes the hell out of it. He told everyone about it. We ended up buying it for our father and our neighbor. Now people will buy at work too. They are ideal for working outside or in dark cold rooms - the light is very bright at maximum brightness. Works fantastic.
