Due to the problem of the original strap with the fact that it starts to smell (I wear 24/7 and during it looks like a shower) I decided to find an alternative. Found this strap. Sent in 12 days. Very quickly, since before that there was a delivery of about two months. Satisfied, look interesting, and now I have a replacement strap for whoop 4

great product given the price. easy to use. just hard to charge with whoop charger.

Great replacement band for the Whoop 4.0. Excellent quality, too. Too bad there are only 3 colors..
