These stretchy and very comfortable straps are a good alternative to the hard plastic straps that came with my Charge 4. Beautiful patterns and colors add a fun and feminine touch to what would otherwise be pretty. bulky device. They don't affect FitBit functionality, and I think they track my sleep better now because these bands offer a snugger fit without being too tight. They also don't irritate my sensitive skin. I am very happy with this purchase!
