I didn’t expect much for under $20 – but all I needed was a heart rate monitor, and this fitness band is accurate as a heart rate monitor. However, curiosity prompted me to test the other features for accuracy. The temperature readings didn’t vary regardless of where it was placed on my arm and leg. These various areas were tested with a digital temperature sensor which revealed different areas on arm and leg varied by 7 degress. The fitness band remained the same at 97.7 degrees no matter where it was placed – so, temp too high and it appears to yield false readings. With steps, as others have said, I also found the step counter to be unreliable and inaccurate. Then, using high-end blood-pressure cuff and pulsoximeter, I checked blood pressure and O2 saturation while sitting and after exercise. I did this several times with my wrist and fitness band held down at my knee, then alternately over my head. None of the readings on this fitness band were anywhere near the accurate readings on the high-end devices. Additionally, the numbers didn’t vary much at all between sedentary activity and exercise. I didn’t expect that accurate readings could be had using a $20 item that supposedly manages all these measures. But, it does do heart rate accurately, and that is why I bought it. For me, I would not rely on this device for anything beyond heart rate, after the many scenarios and tests that I conducted.
