I must admit I have a Chinese fitness band (I actually paid £20 for it rather than £30).
Not only does it do everything I need it to do, well enough that I'm happy with it, it doesn't look like some horrible great 1970s retro digital nonsense.
So I have no wish to upgrade it for an Apple one or a fitbit or whatever. Especially as my record of watches over the years is such that I forcibly stopped myself buying any watch over £30 on the grounds that I'll either break it, lose it or - in one case - take it off, leave it on the edge of my desk, accidentally knock it into the bin and have it found by the cleaner at the end of the day. (And yes, fortunately, I did get it back in that last case...)
