Fitbit - Charge 4 Activity Tracker GPS + Heart Rate - Black

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 love the addition of GPS to the Fitbit. It was fairly easy to set up and now I have no problem. I haven't had any other tracker but will stick to Fitbit for any future needs. Also, I love all of my Fitbit 3 bands are compatible with the Fitbit 4. I change the band frequently. It's not just a tracker it's a watch/piece of jewelry. Thank you. Stephanie

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.

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!

Its a great watch overall and I love that I can swim and shower with it on. It also allows you to do challenges with friends or even random people. Only thing I miss is having a choice of watch faces. I haven't seen any that can be downloaded besides the 4-5 pre-installed. Other than that its a good activity tracker.

I purchased this to upgrade from the previous Charge version and it is well worth it. The "extras" add up to make it a perfect upgrade. I don't need a ton of bells and whistles, but I like just enough to make exercise easier. The ability to control Spotify with my Fitbit is awesome! The ability to change the face of the device so I see what is important to me is great. I love the sleep feedback. I could hook up messaging if I wanted to but I don't want to go that far. My fitbit time is mine and I don't want it ruined with the outside world. I also love the clasp.

Fitbit Charger 4 does help he monitor my daily steps, heart rate and adds Zone Minutes. For beginners it should be a perfect fit into your lifestyle and Fitbit Charger 4 should be worn while sleeping because it will continue to track your heart rate.

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.
