I've had this unit for about 15 months and have been totally satisfied with its performance. However, a few days ago the band broke away from the unit so is no longer wearable. I can drop it in a pocket and use it that way but this defeats the purpose of why I chose this series. It has also been through the wash cycle once; forgot it was in the pocket. I like to track my sleep cycles and heart rate so it is basically useless for that now. I've observed many others who have experienced the same problem; must be a defect in manufacturing. The warranty has passed. I rate this 4 stars because the unit itself has been great. My disappointment is only in its longevity issue. Note: all of the gunk depicted in the pic is dried glue. I pretty much knew it was futile but had to try anyway.

I ABSOLUTELY LOVE THIS WATCH!! This is my first fitness watch, I've been wanting one for so long! I've been using dieting and fitness aps for several years and felt that I wasn't getting the right results. With this fitbit and the app I can micromanage everything I do from my calorie intake, daily steps, stress management, menstrual cycles, sleeping habits, heart rate, daily calorie burn, and more! My favorite feature is being able to GPS track my hiking and running routes. It connects directly to my phone and shows my average heart rate, calories burned, cardio and fat burn minutes, inclines during hikes, as well as a map of my route. This watch has helped me lose weight and maintain my physical AND mental health. I will definitely be using this product for a long time into the future. You can even connect with other users and friends on the "fitbit community" section of the fitbit app, making it easy to keep up with challenges with friends and family. Very comfortable to sleep with, easy to change bands, and I charge it about every 4-7 days depending on how often I am exercising and using the gps feature.

This is the best tracker I have used, I bought this to monitor my heart beat and its so accurate that it was exact match to the numbers in a hospital machine that was hooked up to me. This design is so sleek it just looks like a band that I can put on my other hand when i want to wear my favorite watches.

I was debating between going all out with an Apple Watch or a Fitbit and I’m glad i chose this product. I just want the basics of my steps and heart rate and to track my sleep. This gives me what I need. The difference with the charge 3 is this has Spotify connectivity but honestly it’s garbage and you may as well just listen on your phone. But again if you just want the basics this is free at and connects well with Fitbit app.

With this Fitbit I am able to track my sleep, my motion/steps/exercise, and my calories. It’s fantastic to help with personal accountability. You can input your own exercise events (and get credit for the calories burned), search thousands of foods & name brands, and understand your heart rate daily. Great purchase!
