Review (3/5): Don't look for a "grip" from these bands... offers added friction only.
This does not keep a lace front from blowing away from your edges. This is not a substitute for glue. In the wind, sis, you will be embarrassed without something else to keep those edges down.
These bands make it a little harder for the wig to slide backwards but the wig has to be tight in the first darn place. It's really just added friction. You'll be disappointed if you buy this expecting a "grip".
The velcro closure is cheaply made, big and bulky but manageable. I'll use what I brought but am not sure about a repurchase. I'll update after I can gauge the durability of the bands.
