Fitbit Sense Advanced Smartwatch with Tools for Heart Health, Stress Management & Skin Temperature Trends, White/Gold, One Size (S & L Bands Included)

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

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.

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.

Am using it since 3 weeks now.going for 120 to 155 bpm , walk, jog run combo for an hour on alternate days.Wearing it during sleep also. Love the sleep data analytics.Like the heart rate analysis as well.Sometimes step count may look odd considering no real walk may have been done,other activities like handwash, opening/closing door too seemed to be counted !!Can live with this oddity :-)Syncing with bluetooth/app twice a day. otherwise keeping it disconnected from mobile app.To save battery. Turned off Always-On Displayand using wrist rotation to wake up screen.on an average , able to go 4-5 days without needing to charge. Charging with battery hits 10%.

I have been using fitbit trackers since 2016. Have used Fitbit Charge HR, Charge HR2 and Versa. I purchased Sense, thinking that the product would have matured by now (It was launched 2 years ago), and fitbit would have fixed all the issues. I like all the different metrics this device can capture. But in the end, this is meant for tracking fitness, where it fails. The heart rate tracking during exercise is highly inaccurate.During 13 minutes of cardio exercise on an elliptical bike, it showed heart rate 110 most of the time. Fortunately, the bike had a heart rate sensor, which was reporting HR around 150. At the end of my workout, the Sense reading suddenly jumped to 150. It also happened during strength trainings, the Sense reported HR below 110. This is very frustrating.There is no fix for this issue. On the official fitbit community forums, the customer care is just silent. So many people have reported this issue over last 2 years.

Received the replacement in 2 days immediately after the faulty watch receivedGood build quality with features loaded , Charge withstand for 3 days and the to charge fully it takesonly < 2hours , Captured ECG and downloaded report appearing to be useful during emergency.I got up from bed and noticed already completed 50 steps and not sure how the step count increasing while sleeping need to further understandHappy with the Fitbit smart watch over all quality , not sure why so many negative feedback which actually delayed my purchase decision

The product @around 18k is not what you expect. OS and software experience is unpleasant. Below are the some of the quirks of the fitbit:1. You can install spotify on the fitbit but only for controlling playback. You cannot download a single song on the watch itself.2. You can know your SPO2 reading only if you install and use a particular watch face. You cannot measure spo2 on demand.3. It consistently shows weong HR on treadmill.4. Charger has a faulty design which will definitely result in one of the pins getting stuck and charger not working.5. Provided band not vey comfortable and difficult to wear.6. Apps on fitbit store is a joke and are simply useless.7. Screen will easily scratch. Very low quality.8. You have to manually sync everytime. Automatic sync rarely works.9. GPS locking takes a long time. Sometimes it won't use GPS even if you are on open road.Overall its a bad device with very little going for it. Don't waste your money. Go for something other than fitbit.

Every seems fine but auto sync is problamtic and bit costly and navigating on screen is confusing.
