Great purchase
Great purchase quality great upgrade and better than the standard strap also great if you do water sports. Also much better for every day wear as you can shower and not worry about having to dry the band off. Much more comfortable, also durable.

remarkably delicate for a supposedly rugged band...
This band started falling apart after 90 days. The "soft-touch silicone" began peeling like a bad sunburn, leaving gross rubbery bits on my wrist and sheets. The clasp mechanism loosened to the point where it would randomly pop open during workouts. essentially a glorified rubber band that any competent manufacturer could make for $2. The material quality is embarrassingly bad for something meant to be worn 24/7. It absorbed every smell from every workout and never fully dried, developing that special gym-bag funk that no amount of washing could fix. The kicker? When it inevitably breaks, you're locked into buying another overpriced WHOOP band because of their proprietary attachment system. It's a subscription model for rubber straps. Save yourself the frustration and skip WHOOP entirely. But if you're already trapped in their ecosystem, at least buy the cheapest possible band. They all fall apart equally, anyway. Poor value, poor functionality.

Well made, fits well for big wrists
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.

Very good
I bought it for when doing sports and it works very good. However, you need to remove it quickly if you either sweat a lot or swim (both my case) because it does not dry easily and your skin might get smelly or sore. Once WHOOP came up with the new smaller version I decided not to buy this again and instead bought an extra regular band that I can wash and wear it more often as the plastic one.

My favorite whoop band.
This is my favorite whoop band. I've tried all the whoop bands. It drys quickly. It's a very durable band. It feels the most sturdy of all the bands offered. I've had this band for a month and I love how it wears.

Great Band for the Gym
Band seems to be of high quality. This is a great band for the gym in terms of comfort and water resistance. My order was placed easily and delivered on time and without issue.

STRAP GETS STUCK AND WONT COME OFF — AND DAMAGES YOUR DEVICE
I’m writing this review to express my deep frustration and disappointment with my recent purchase. I was genuinely excited to finally get my hands on a Whoop band. I had high expectations, especially given the premium price point and the reputation your brand holds. Unfortunately, those expectations were completely let down from the moment I opened the box. As soon as I tried to put on the sports strap, it got stuck and now won’t come off. This happened right out of the box—on the very first attempt to use the product. I followed all instructions carefully, and yet I’m now left with a brand-new device that I can’t even wear properly. This is absolutely not the experience I anticipated from a company that markets itself on performance, innovation, and quality. I feel incredibly let down, and quite honestly, regretful about my purchase. I attached and sent a picture to Whoop’s team of my hand’s injury while tried to remove the strap. Not only was I disappointed with the quality of the strap and product but also to learn that the application and process of changing the strap is dangerous.

Ottimo bracciale morbido e asciuga presto

With that price for the band, it should fit perfectly. However, not the case with this band. It’s suck on the device, and very hard to replace them.

Also für den Preis müsste das Band perfekt sein. Ist es leider nicht, das Band ist nicht perfekt plan mit dem Sensor. Schaut einfach unsauber aus.
