I'm very picky about the hair ties. These are good, don't get tangled but I did find they lose their tightness quickly.  For example, I put one on my wrist every day, if I put my hair in a bun it is almost falling off my wrist the next day. They do the job but in my opinion I have to throw them away pretty often.
