I don’t know anything about that specific model,

But, I have the charge 2.

It tracks my my heart rate, steps, stairs, calories burned, the specific exercise I’m doing and my sleep. I can also set alarms on it. It’s easy to log in the food I eat with the app. You can set a calorie goal yourself or you can have them set it for you.

The reason I got the charge 2, is because I can get text notifications. So if I’m at work and I get a text, my Fitbit will vibrate and I can just look at my watch without taking out my phone.

I got mine on Black Friday weekend 2016. It still works great. Price wise, since it was that particular weekend, I paid $170 with the 2 year warranty.

It’s been amazing. I’ve lost 30 pounds. It’s also helpful when I just use the app.
