I have been using the Mi Band for years which I generally like, although it’s quite a simple device
@cinaed666 @twotone I also have the Forerunner 55.
Something to note is that Garmin watches are Linux-friendly and can be used without signing up to their cloud services. You can access the watch as a USB storage device and manually grab the .FIT files on it, which you can then import into tools of your choice (or convert to .GPX for wider compatibility).
