is defective producing an inaccurate HEart Rate

Before it died, I was unhappy because it was uncomfortable to wear and did not give accurate heart rate readings as compared to clinical heart monitors attached simultaneously with Fitbit, but it cost $250; so, I kept using it

I’ve had nothing but problems getting an accurate heart rate

Accurate heart rate without the inconvenience of a chest strap

When working out the pulse rate is commonly not accurate by a lot, usually low, although at times it will read way high.

Despite the facts that it tracks well and has accurate heart rate, it has 2 big flaws

The tracking really is good (heart rate, mileage and etc.

While the watch functioned it was great, sleep tracking excellent, heart rate, etc.

The FitBit Surge works as it should
