I love these! I've never used coil/spiral hair ties before, so I didn't know what to expect but these work on my very long, heavy, thick, curly hair - even when it's soaking wet out of the shower! It holds my hair exactly in place with no loosening (which inevitably happens with every other hair tie I've ever used). You may also notice that they might stretch out a little bit when you take it off after wearing for a bit, but then a few hours later they're right back to their original size! Thoroughly impressed and I will keep buying more. Affordable and excellent product.
