I bought 2 watches - one for me and one for my mom. And when I put them on my right and left hands to check if they show accurate measurements - they showed different amounts of steps and absolutely different sleeping cycles. As I was wearing both of them 24 hours and they showed difference in almost everything. Very disappointing. As they looks good, but you buy them not for their looks. Differences were not small - in steps for around 500 steps difference. In sleep cycles - just 2 different cycles at all. Both watches were put on exactly the same settings and put on hands in the exactly same positions. Very upsetting.

The design is nice, feels good, but the registered data is far from realty. I wake up with 200steps made, during non active day it registers over 10.000 steps easily. on active day it shows 26.000 and up. It was more precise during first 2 weeks. Same with the sleeping monitoring. I like the sports mode and values it takes, but at this point, I cannot be sure it is accurate.The alarm is loud and cannot be silenced or changed.
