surundoNylon Sport Band Compatible with Whoop Band 4.0 Strap Men Women with Bumper Case, Breathable Nylon Adjustable Waterproof Replacement Wristbands Straps for Whoop 4.0

So easy to use, love the variety of colors and fits Charge 6 perfectly

The bands were exactly what I expected. Easy to put on and the colors are good. Love the double clasp.They also are very flexible and comfortable.

Fitt my Charge 6 beautifully and snapped on easily. There are other ones available that are three times more expensive but no better looking and probably no more durable....

Nice band, nothing fancy, but made out of a material that I can keep on for swimming and showering. Good value. Initially I was concerned because it doesn't have a standard type buckle, but haven't had any trouble with them in several months. Fun to change out colors

I am wearing one of the bands for over 3 months now and no issues. I have skin issues and I have not had any adverse reactions as long as I take it off occasionally for showers and charging. I have not had to use the other bands as the first one has lasted well enough. the coloration on the metal did rub off so it's not perfect but I don't mind that minor issue, I think for the price this is more than I could have asked for.

These colors are really nice. I like how many different options come in the one package. They are easy to attach/detach from my Fitbit and stay on once they are attached. They are comfortable and breathable. It's winter now, so can't say if they'll make you sweaty in the heat, but during workouts they have not caused sweat issues.

This product felt like a scam. Clasp was very cheap and flimsy. The end piece that you slide on would not stay securely on the Whoop 4.0 without sliding off easily. Worst of all, this strap wouldn’t properly clasp onto the Whoop 4.0. I would not recommend this product and strongly advise to look elsewhere.
