This band by mi is poor in quality and the battery was the worst thing in this band .battery drane in 2-3hours of regular use and somehow it irritate you during running and its not buld with military grade so dont buy this band.
Initally it shows the result very nicely but after upgradation this thing stop showing any result so I want to say only one rhing ti mi and the customer service team that if u know that you product dont meet those standards of other fitness band stop cheating your customer.
