I have a Fitbit charge3 and I really like it. I have only had it for 6 months, so I can’t speak to it’s reliability.
The only thing I wish it had was an alarm that would wake me up at a specific level of sleep, like rem sleep.

The OS on it is quite nice, the iOS app isn't bad either, but the inaccuracy just drove me nuts.
I moved on to a Garmin vivosmart instead. Not quite as pretty, but a lot more accurate.
