## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Watch
*by S***E on 9 April 2022*

I have been using it for few weeksBattery capacity is not an issue, as due to fast charge it gets charged from 20 to 100 per cent in one hourSleep tracking is goodHeart rate is accurate except during exercise where it is accurate 98 %,Health Metrics is a good feature - spo2, hrv, respiratory rate are very good health indicators. ECG, breathing exercises and EDA scan are goodStress Management and readiness score are based on algorithms and may differ from person to person and under different set of conditions - not convinced about the accuracy of these two measurements. One has to accept or reject these intelligently and ony approximately

### ⭐ Worst Service Infact No Service in India
*by R***I on 22 March 2025*

Am writing the review after 18months of usage. The watch has damaged. The software got corrupted. So when I try to turn of the fitbit it gives me fitbit logo then it blinks and gives a Red X on screen. When I checked with the Customer care they say the watch is out of waranty and there is no repair option nor a service center in India. So wasted my money. I would highly recommend you check for the service center availability in India before buying such products.

### ⭐⭐⭐⭐⭐ Fabulous but need some works!
*by L***K on 22 May 2021*

Go for this smartwatch only if you don't want any gimmicks that other smartwatches may offer and requires pure overall health tracking. It has accurate and precise health tracking ability. Only thing that it should improve or have is to play songs from Spotify through watch speaker itself.
