I used a fenix3 for years until it died. (it went into a boot loop and would not respond)
I replaced it with a fenix5X which I received as a gift.
A few days ago my fenix5X stopped charging - and at 3% it switched off - currently black screen and unresponsive.
I have tried all resets suggested on the forums but no luck - Have tried several power outlets, purchased new charging cables - tried syncing to Garmin Express all without luck.
I have emailed Garmin CS and had a fast reply - but they cannot help because I don't have my proof of purchase.
I have had two Garmin watches - both have died for no apparent reason and I am pretty disappointed at the lack of reliability and also with the poor customer service.
These two watches are now heading for landfill - which is a real shame - as Garmin have not been able to help fix the problem.
I will not purchase another Garmin product and will warn my friends to avoid.
I think I'm going to buy a Wahoo.
