The issue with the wahoo is the contacts corrode. Seems like they woulda thought about this for a product designed to be used while sweating… You can try cleaning the contacts with some alcohol and even 800+ grit sandpaper if theres any visible corrosion on it. I put a small dab of oil on a q-tip and coated the contacts. So far seems to be working. I’m on my 3rd (and last) warranty replacement Tickr
The easy answer is to just get the Polar!
