I have been using the Mi Band for years which I generally like, although it’s quite a simple device
Man, I loved my Fitbit One, but damn was it so fickle. So easy to lose and not waterproof, and spotty bluetooth. It was just a basic pedometer with calorie calculations.
FWIW I have an Inspire 3 and it’s reasonable. It has a chime to find it, Bluetooth seems solid enough, and it’s definitely waterproof as I run it under the sink to wash it every day. Cheap, too, so I don’t really care if it breaks. Small, so not a big, clunky fashion statement or something.
I just wish it tacked my heart rate a little better while I’m working out. Mine loses track what seems like immediately once I start sweating a little. It can recover with a little jostle or sometimes moving the band up a notch if possible, but man it’s annoying.
