Review (4/5): With realistic expectations, these are a good buy.
Hoping to settle the dispute over whether these headbands are sized for adults or children. (Included pictures on my husband as we have similarly sized heads but he has no hair to get in the way.) I'm used to headbands hitting below my ears which these do not. If you agree that that is the proper way for a headband to fit, then these are best suited for children.
Since I just wanted something to keep my hair out of my eyes without sliding out constantly, these work fine for me. I used a pair of pliers to straighten the ends so they wouldn't poke into the backs of my ears. For the price, I'm content.
