Review (5/5): They're great--just customize them to fit your head!
I now understand one of the comments that I read about these being for children. These wire headbands are considerable shorter than "normal" headbands. It took me a few hours to get used to them. But here's the advantage I discovered: I wear glasses, and these are short enough that they don't interfere with my glasses. I used to put on my glasses, and the ends would push back on the head band (and dislodge it), or I would have to put my glasses over the headband (and in turn, I'd get a headache from the pressure). So once I maneuvered the headband to fit the shape of my head, and the teeth downward to catch my hair properly, it works out quite well. Can't beat the price for the quantity. And the price was low enough that I was willing to take a chance on this product not working for me at all.
