I often don't leave feedback, but this deserved one. I love the fact there were two sets of bands included, and two different sizes included. I can't/don't wear as a rule, silicone bands, and was glad they included the fabric one. The pricepoint was hard to beat as well.
The Charge 4 special edition has everything I need and looks great with the band that came on it. John
Love it. Easy to workFYI U have to enable the heart monitor on the watch itself. Not the app
I am still learning what all I can do with this Fitbit!
Nice upgrade from the charge 2 I had...works great!
Helping me lose weight track my calorie intake etc, have to take calories out with a grain of salt as the step counter is obviously not exact. As long as you have a fair idea have much exercise you have done no problems.
I really just want a watch and fitness tracker without any of the other things smart watches bring. I find it generally comfortable on my wrist, not quite as much as I would like
15 year old grandson likes it
My kids loves this Fitbit and it works as advertised!
Awesome fitness tracker. Way better than the Apple Watch I had before as its less intrusive on the wrist as well as being so light that I barely notice that im wearing it. The battery also lasts more than a week and also charges extremely fast compared to other fitness trackers.
