This product is definitely a band that he must avoid, I'll receive my third bracelet in 8 months, I definitely think this product is not reliable, and that is disposable, or up to the moment the guarantee no longer covers the product . I asked for a replacement with UP24 without success, hoping that it would be more reliable, but it was denied (obviously, otherwise everyone would do it)
I find it shameful that even Amazon continues to reference product with such negative opinions ...
