Very long lasting!
I tried my first of this set of bands 7 months ago.  And am still using the same one band I started with, every day & every night, seven days a week.  It’s beginning to get a little stretched out.  But I’ll forgive it.  Amazing durability for anything elastic.  Doesn’t catch my hair hardly at all, never gets tangles around it.  Very happy!
