Not impressed. They're just your typical elastic resistance band. Honestly exactly like the ones I bought at the dollar store for $3. They are also too large. I have to spread my legs out pretty far to keep any tension. It came in a nice carrying pouch and they are cute (as far as resistance bands go) but I have no idea where they get off charging nearly $20 for them. I don't know what I was expecting but I was hoping they wouldn't roll up my legs like my cheap bands, but they do.
