At first this band is too bad. because it looks ugly. but its rubber band feels comfortable in our hand. Mi say that about this band it gives 20 day battery backup. it is tottaly worong because we this is new battery backup it too good but when we use daily it reduses his battery backups.
it is may be user friendly but as my tech lover experience it is too bad to use.
at last its price is good then other band in market
overall it is not soo good but no so bad
