Zookr.in i Overall the product is amazing, but the battery backup is not same as they claimed to be. They are advertising as the battery will stay put for almost 20 days, but that is not entirely true. If u are using the notifications features and connecting to the phone 24/7, u can expect to last it for 10 days maximum. Other features are excellent like the find the phone, pedomter, heart rate measuring are all very good. Even the display is too good comparing tothe older version. The band strap also look premium. I suggest it as an excellent buy from zookr.in
