Bluetooth coverage is 1 to 2 Mtrs max. Technically This will not solve ur smart watch dream. Don't purchase or u will regret..I had ordered for replacement also and same problem found in other product also..this means it's s manufacturing problem.. 2nd issue very delay in process 3rd issue it's having touch than also u have to lift ur arms to see the watch..one tap option not given. 4th issue vibrator is not so strong like Mi Band. request to go for other watch not Noise clorfit pro 2..
