Update from Versa to Versa 2
Rating: 5
This is my second Fitbit. As a heart patient it is nice to see that this Fitbit seems to be a little more sensitive to my heart rate, comparing it with a polar chest wrap. Very easy set up and a great app that goes along with it!! Great value when compared to an Apple iWatch or a Garmin

Very comfortable, it was my first purchase of any fitbit and love everything it tracks. Setup was a little diificult for me, but I feel its because I was not familiar with the set up and app. I have no issues with it connecting to my phone and registering the alerts from my apps or messages / calls...`

I LOVE THIS WATCH!
Rating: 5
Fair price and quick shipping Great watch! I did a lot of research before buying this watch. I had a Fitbit for years, so I wanted to upgrade to a watch that had more capabilities. This watch it's fantastic, if you want a watch that truly tracks your steps, heart rate, calories burned, get up and mover reminder, you can program it for a number of workout activities, helps monitor your diet and health, and has perks as well! So many ways to customize this watch to fit your everyday needs, news app, weather, Spotify, etc! I know most people want an Apple Watch, but this watch is way more realistic to actual life needs! It's lightweight, not too big or bulky! Very sleek look! I recommend this watch to my son, and he loves it as well! I would recommend this watch to anyone!

Good watch but poor quality
Rating: 1
I bought this in Nov 19 . It is a very nice looking watch with lot of good features. I absolutely loved it but the build quality of $200 watch is poor. I used it almost daily but very moderately. Last week, within 7 months or purchase, the glue holding the face of the watch broke off and now the watch is unusable. I am totally disappointed with this. I will not recommend this watch

Didnt live up to my expectation
Rating: 1
Got it for the purpose of being able to see my texts/calls and it managed to get every notification other than those two. Isnt an awful product it did everything else correctly, but I got it for one main purpose and it didnt deliver so theres no point in keeping it.
