Forerunner 245 reliability

After 3 years with Garmin Epix2 one of my buttons started to miss hits so I've sent it for exchange. Meanwhile, I grabbed my old good 245 from the drawer and... nothing worked:

- it doesn't pair with the phone stuck on "Initializing" animation

- it doesn't pair with the HRM Pro chest strap

- it takes about 10 minutes to acquire a GPS

- after Wifi or Garmin Express sync it doesn't show anything in Garmin Connect: no sleep, no body battery. However, I can see it on the watch.

I am now requested to send my device for an exchange but of course, it's outside of the warranty. I guess it doesn't seem to be a very attractive option to pay for a refurbished one that could have the same issues a few months later.
