Must admit this is a brilliant fitness tracker. It has a soft comfortable silicon strap and has a domed face which appears to magnify the screen. It is easy to read and touch screen. You can download the IXFIT app off Google Play, then pair it to synchronize the clock. The battery seems to work well it didn't need a charge for a week out of the box. The blood pressure monitor seems very accurate too. It's price is very reasonable too.
