Absolute value for money
This is my 4th FitbIt watch.. first was a charger (still works perfectly) then it was ionic (google paid $200 back) and then it was Fitbit Sense, died recently after 3 years of rugged use and now this. Battery life is amazing, tracks your fitness perfectly, good enough for swim and outdoor sports. Looks good and absolute value for money

Infinite encyclopedia for fitness!
Till time ( right from 2017) I am using an Indian app & tracker GXXQX. As recently switched over to fitbit tracker & app with premium subscription, my journey is on with a tracker "Infinite encyclopedia for fitness", after fed-up with Chinese trackers. I can not boast like Fitbit is this good, that good etc since there are multiple features and most advanced options like EDA SCAN etc still I am becoming myself familiar as well as conversant with Fitbit style of fitness measures - habits. 200% worth for moneydpent on tracker & subscription with Fitbit's top-up benefit of six months free premium usage. I will review again after six months with the benefitsI have experienced.

Great watch with not so great gps
Nice watch, looking good and minimalicstic, great fitbit app and battery life, lots of helth data. Problem started on first bicycle ride - watch couldn't find gps signal, so of 30 km ride took only 3! km of measurment. Tried to check on other location - same story. Returned because of not working properly gps module - found same issues on fitbit community. Applied to customer support, though it was stated that normally takes 24 hrs for response - still didn't recieve any information. After all - maybe that's just my luck with current device, but mention that you may face same problem, so won't recommend that product for activity tracking

Battery dies after 18 months.
Good smartwatch while it worked. For 18 months it worked very well. Specially smart wake up alarm and workout tracking. Ater 18 months of normal use the battery started to last only few hours or even minutes.
