I had the Fitbit Charge 2, then the Ionic. The Ionic packed up when water got in and Fitbit wouldn't replace it. I preferred the Charge 2 because it uses GPS from your phone, so doesn't flatten the battery in a couple of hours when using it to monitor a bike ride or very long run. The battery in the Charge 3 lasts much longer that the Charge 2 (12 days vs 5) and everything else seems to work better. The functions are more or less the same. You can find detailed online reviews that explain the differences. I use a Fitbit mainly to monitor my heart rate during sport. I recently got incapacitated due to blood clots in my lungs, which is what prompted me to get another Fitbit after my Ionic packed up a year ago. It's really good to be able to see what happens to my heartbeat as I get back to normal health. I can see when I'm pushing too hard. Some people say that the heartbeat monitoring isn't reliable. All I say is that there is a clear correlation between what it shows and what I'm doing. I think it's more than accurate enough to give you a good idea of what's going on with your heart. Note that the Charge 4 has a lot of new features, one of which is its own GPS, so loses one of the advantages of the Charge 2 and 3 regarding GPS battery life for long sessions.Read full review

My third Fitbit and this is the best yet, all stats are pretty good not spot on but good, plenty of watch straps on eBay to change it about a bit. Really do forget it’s on it’s that comfortable. And battery lift is 5 days between charges. Notifications from iPhone where you can cancel call and read text, plus many more notifications can be set up ie calendar, WhatsApp and alarms. Excellent value for money
