Review on ShuYo Adjustable Elastic Watch Bands: The Perfect Fit for Fitbit Charge 4/3/SE - Soft, Breathable Replacement Wristband for Women and Men by Michael Long

I've been wearing the Charge 2 24/7 for two years with a one-piece rubber strap. It was pretty good. I bought the Charge 4 and this is the fourth series I got for it. Other inelastic nylon straps don't stretch and are too tight, and some are too short. This bracelet is the most comfortable. I adjust it loose enough that the fit is comfortable and I can move the watch up and down my wrist, but let's look at the heart rate anyway. It doesn't slip on my wrist and I don't wake up with bracelets on. And when I run, I don't have to adjust the belt. This is the perfect strap for this watch. The elasticity makes the watch feel lighter, like an elastic camera strap works. Buy this bracelet if your watch is uncomfortable. The band is also breathable, so don't sweat underneath it.
