Be careful while receiving this product, as i received a refurbished used product, the bottom glass of the sensor had scratches and can come to know it's been used before. Regarding the product, is good, is mostly accurate also, vibration for alerts is very strong, steps counting, blood pressure and pulse all accurate, battery backup is also good. no problem for connecting with the phone, everything is working well only thing is i feel cheated for getting a used/ refurbished product.
Reading for blood pressure are not at all accurate. These are just numbers. HR is approximate. Bluetooth connectivity is very poor. Band gets disconnected again and again even if kept aside. Steps counting & other features are ok. Light weight.
