Is anyone else having any issues with the Wahoo kickr core? I have 2 purchased within the last 60 days. 1 seems to work fine. the other quit broadcasting power. I waited 5 days for a replacement which had the exact same problem. Going to their FB page it seems that this is a BIG Problem with several people reporting the same issues. I am really worried he working one may develop this “problem” down the road (out of warranty), and then I would be out $900. Just curious if anyone here is having any issues.
