Very good recommend
Exact same as on website but cheaper and free next day delivery can’t go wrong came in exact same package the cheaper and quicker. Value for money, fast delivery and works well. So small this is the second one we’ve lost! Hopefully won’t have to order again… but absolutely no issues with product

Did not work
I found the battery did not charge up. I left it on charge for hours but still no output I have subsequently cancelled my subscription to Whoop. The battery was not the only thing that did not work for me
