I have used them a few times and washed them twice. The black and white one are fine, but the gray one ripped at the seam during the first wash so now it's useless since it won't stay put without the sticky band (which is floppy and useless now).

It was a great deal for three bands, but not so
much for two bands that I'm afraid to wash.

(Attemting to sew the seam back up)
