I just replaced my Fitbit Charge 2 (after 4 years) with the Charge 3 and I love it. I read the Amazon reviews before I bought and I found some of the old reviews (2018) are simply NOT correct. Several say the face clock doesn't provide the date - incorrect! I provided a picture to demonstrate this is false. The battery is longer on the Charge 3 and has lasted up to 7 days, although I typically charge it while I'm in the shower when I want to juice it up. Several other reviews give lower stars because the Charge 3 is not like their previous Fitbit (diff model) - well guess what, that is why they have so many different products to choose from. The best way to find the Fitbit product best for you is to go to Fitbit.com/compare and use the "Select top feature" drop down and select the most important features you are interested in having... this will show you which product to choose. Here is what was important to me... 1) Steps 2) Sleet tracking and stages, 3) Reminders to Move, 4) Hourly activity, 5) Swim proof and tracking, 6) Cardio Fitness Level, 7) Call, Text, calendar, and smartphone app Notifications. With these features, I had 4 products to choose from. I went with the Charge 3 because I really liked my Charge 2. Charge 3 has a longer battery and other additional features besides what I already listed that I'm sure I will learn to use. One of my favorite features is the ability to set how many steps you want to get in each hour. If I haven't completed my steps each hour, I get a notification that I need 52 more steps, etc... to meet my goal. It's so easy to get busy that this is simply a great reminder! It is so much easier to meet my daily goals when I start early each day. My other favorite thing is the Fitbit app, website and health tips newsletters via email. These tools unlock insights and inspirations. A friend told me she was going to get a Dr appointment to check for sleep issues - I asked her if she had looked at the Sleep tracking and information available on the App/Website and after looking at this info she decided she didn't need a Dr appointment. Information is powerful - make sure you are aware of all the data Fitbit provides at your fingertips! I've have experienced a few problems with syncing, but primarily when I fly and change time zones. A simple solution that has worked for me is to plug in Fitbit to recharge and that seems to fix it for me. I have to say this is the same for ANY Bluetooth syncing device, not just my Fitbit. Another tip is there are lots of bands available for the Fitbit on Amazon and other places for very reasonable prices, so you can change the color/band to give you diff styles for working out vs an evening out. Enjoy!
