Worked for 31 days and then died...
20 September 2018
The 31 days or so that I used the HRM-Tri with a Fenix 5x were ok. Then it died and my troubles began. By the time I troubleshooted the device I was out of the return period to the Seller so I had to contact Garmin directly.
The Garmin Support system is notoriously bad. I spent one hour holding, proving that I taken all the necessary steps to try and fix the problem. Including having to reset my Fenix 5x settings, even though all the other devices (foot pad and cycle power meter) worked fine.
Eventually, after I replaced the battery, the Garmin agent agreed the unit was probably faulty. I then had to provide proof of purchase, and am now awaiting an RMA number so I can send the faulty unit back. *If* Garmin identify a problem, and they have a replacement unit available, I will receive new unit. This entire process has/will take weeks.
Never. Will. I. Buy. A. Garmin. Product. Again.
