Review on ShuYo Scrunchies Bands Compatible for Charge 3 and Charge 4 - Soft Elastic Fabric Replacement Accessory Strap for Women and Girls by Mark Grady

I only really wear black as I always planned on repeating the other two with my own decorative elastic and the included clasps. The clasps (where they attach to the Fitbit Charge 4) are textured plastic and are very secure. The style is cute and I bought them because I like plastic clasps more than metal clasps. I have fairly thin wrists and they are snug but not too tight. If you have medium sized wrists they can be a bit tight. The black scrunchie is very comfortable even if your wrists swell at night. I didn't wet them so I don't know how fast they dry. I think I would switch to a different swimming group.
