I purchased a HRM Pro Plus directly from Garmin. It is defective. I have sent perhaps ten e-mails to the support e-mail address and have not received a response.
I am well acquainted with the vagaries of these devices. I know that they take a while to lock on during the winter. I've replaced batteries in my HRM Run and older Pro straps (which is a pain, and which is why I purchased the Pro Plus. This is not the problem.
How do I contact Garmin to resolve this matter?
Thanks for the help
[NB: Been running with Garmin devices for 15 years. My current device, a 255, works pretty well. I've not had most of the problems the people in the 255 boards report]
