Review: Awesome - Way better than the cloth bands!
Review: A Change in Material from Whoop Straps - This a different material than the weave that came with my original stap. It was easy to attach to the sensor. It is very comfortable. If you have very large wrists, this may not fit. It seems to be more waterproof than older staps. desertcart delivered the stap in 2 business days.
