So, Garmin has offered me a replacement Forerunner 735xt for about £100.
I can’t remember how much I paid for it and when I tried to check on Wiggle, it look like it has been discontinued.
I’m considering not to buy it and try something else. To be honest, I only want an activity logger, i.e to record the days I ran or cycled – anything else is overkill. would a fitbit do that for me?
