Review on 🔵 Joyozy Sport Waterproof Bands - Compatible with Fitbit Charge 3/Charge 3 SE/Fitbit Charge 4 Smartwatch - Silicone Small Breathable Soft Strap Replacement Wristbands with Air Holes - 2 Pack for Women and Men by Marcus Cross

I ordered black/turquoise and black/yellow straps. The straps are comfortable enough. I was hoping for a little more air circulation than with other sports bands. I was wearing the sea green color and the strap broke after about 3-4 months of wearing. The break was where the strap connects to the Fitbit. I took the strap off about every month to clean it of dirt. I used a cotton swab dipped in rubbing alcohol as recommended. Switched to yellow after the aqua broke. Unfortunately, the same thing happened to the yellow one after about 3 months. There aren't many thinner sport band options for the Charge 4, so if you can switch every 3-4 months it should work.
