I've only had one bluetooth device, a Fitbit, that actually worked with any kind of reliability. From time to time I still have to bang it on the side of my phone to get it to pair back up.
I’m a massive fan of Fitbit devices, they work great. But the same can be said of my Plantronics BT headphones, which I’ve used daily for almost three years, same for magic keyboards, mice and touchpad of different generations. Truth to be told, any cheap device that wouldn’t work reliably (I can think of a few BT headphones in the past) I just tossed or returned when possible.
