The eldest FlyingOxJr has shown repeated interest in mine and the wife’s Garmin watches, but he’s only 10 and I don’t want to chuck a whole lot of money on something he might fall out of love with after the novelty has worn off. Conversely I don’t want to get a cheap tat one where he’ll fall out of love with it because of the cheap tattiness. Is there a reasonable middle ground?

Does he have a device to run an accompanying app?

If so, Fitbit software (UI and how it interprets the data) is very good IME – and worth the premium over a cheaper device.

He’s got an Android tablet but no phone yet – we’re trying to hold off on that until he heads off to high school.

My son had a cheap Amazon tracker and it was rubbish. Strap kept coming undone, step count was erratic and all in it it was a waste of £25. On the other hand my nephew has one of these and it looks really good – https://www.garmin.com/en-GB/p/711538/pn/010-02441-03
