One star as there no option for no stars.I have an Edge 810 on which the bracket fixing has broken. No replacement or repair service from Garmin but they do offer a trade in service with 30% discount from their website prices. I asked about the Edge 520 which is £250 on their website so less 30% is £175. The same price as I can buy from Decathlon. They also said it was no longer available so I needed to buy an 800 series which is, of course, more expensive. This is the second time I have had this problem with a Garmin so I am now going to buy a Wahoo. Cannot be worse.
