I have been using his from 5 months. I bought it online from flipkart just in rs1200 only.
I like it the sensors are very good and accurate they are working perfectly and it has a good battery backup we can use this in any smartphone without any issue its very awesome it makes our lifes tasks so simple and it looks very nice and impressive on wrist just like a watch very cool. one more thing about this is the design the build is very excellent it has perfect design and its very easy to use so u can go for it blindly.
