I have read some reviews saying this band isn't built well or unsuitable for bigger wrists. In my experience, it is not only constructed incredibly well but also fits my wrists, and I am a bigger person with big wrists. The product overall is pretty self explanatory - rubber wrist band as opposed to the cloth.

This band is great if it would not break so fast. The metal clasp that holds the band on your wrist is apparently only held in by a cheap glue. I had the band for less than a month before the clasp broke rendering the band completely useless. For such a high price tag for a band I would expect much better quality. Very disappointing.

Really convenient to have a totally waterproof and quick drying band for running and showers.

Looks good, but it was not easy to install, and I was afraid to break it

It was really hard to put on the whoop and had to use a hammer to take it off. Once it was on, it seemed like it did not fit right on the whoop as it keeper coming off to the side. Will not buy again for sure but still need a band to exercise.

I like the band color and texture. Only problem with it is that sometimes the whoop doesn’t work well. Not sure why.

The regular WHOOP bands are not aesthetic whatsoever regardless of color in my opinion… so I am happy that they have decided to come out with this option! Hoping they continue to improve the aesthetics of their bands but I am thrilled with this band for now as I’ve had WHOOP for over two years now!

Alguien más tuvo el problema que para meter el sensor en el gancho estaba súper duro?

Llego perfecta! Y es mejor que con la que viene originalmente ya que está de seca más fácilmente.

Terrible product. Was difficult to get the monitor in the strap and then near impossible to remove. Check Reddit. MANY people had issues removing the censor from this strap. If you intend to ever change straps, this isn’t for you.The silicone itself is hard to describe. It looks and feels ok but every single piece of lint, dust or hair sticks to it instantly. Not at all like the Apple silicone bands.I liked the look of it in photos which is why I ordered it. In person, it looks too much like you’re wearing a second watch. Needless to say it’s also overpriced but so are the other straps.Would not recommend based on the issue of removing the sensor from the strap. And no, mine wasn’t an isolated case. It’s a flawed design. Do a google or Reddit search.
