Review (4/5): Holds great, doesn't rip hair with this trick
I bought these a week ago. They really do hold hair much, much better than anything else. The first two times I tried to remove them, they ripped my hair out and I almost gave up. Then I tried doing an extra little step during removal which made all the difference.
Before removing, grasp hair above the Bandz (basically as close to scalp as you can) and hold it (like you would when putting a ponytail barrette in). Roll the Bandz down one time. Then, you can wrap your fingers around all of your hair above the Bandz and continue to roll the the thing down. I've been doing it this way and haven't had any hair come out with them. Right now, these are my favorite ponytailers (and they don't make my head hurt like the regular ponytail elastics do from being too tight).
