Review on 🌈 GEAK Stretchy Band for Fitbit Charge 4/Fitbit Charge 3 - Adjustable Elastic Breathable Nylon Replacement Strap for Women and Men - Colorful Rope/Brown Leopard Design by Sung Shorunov

I have a small wrist (5.5 inches) and they fit great, much better than the factory elastics which never fit me properly even when tightened. And they are very comfortable. In particular, metal fasteners on them are much better than similar elastic bands (with black plastic fasteners). They keep the FitBit secure where the plastic fasteners keep falling off. Enjoy the colorful patterns, especially the rainbow stripes in the sense that "so colorful it actually goes with everything."
