Odor Resistant Bicep Band Compatible with the Whoop 4.0 bands - Breathable Nylon Band for Bicep, Bicep Bands Compatible with Whoop. (Black), 40 cm

I really like the way this fits. It is much more comfortable than the wrist. Stay securely where I placed it.

Excellent customer service, very well made product

This does not fit the 5.0 whoop, worked fine for the 4 for a few weeks but now that I have the 5 I have to buy a new one. Annoying, because it advertises as fitting the 5

The band is uncomfortable and keep sliding down the bicep. Also, it does not come with a c-clamp. Which is fine, however the locking mechanism is not strong at all. It does collect some smell.

Doesn’t fit 4.0. On the right , my regular wrist strap. On the left is this bicep band. Clearly they are not for the same unit.

Does not fit properly onto the bar on latch side. Comes off, doesn't seat properly. And battery will not attach properly with this band. It's a $30 elastic bad, it should fit properly.
