Good Product

They don't pull my hair or give me headaches from long use. They do leave kinks in my hair if I leave in for the whole day or overnight. I find that they do stretch, but if you put them in cold water or in a cool place they will go back to their original size.

Still leaves dents in your hair.

I do not like these hair ties. They are supposedly made to not leave dents in your hair which is totally false. They also stretch out way too much which is annoying because then they are not tight enough around your actual hair.
