My 2018 Core stopped sending sensor data last week. Spoke to Wahoo and they have sent me an out of warranty replacement with 120-day warranty for £250 inclusive of shipping
I set up the replacement and have a model that is producing a knocking noise. I have emailed them and will request a pickup of the device and refund and buy a new one from a different brand.
I’m not particularly pleased with wahoo at the moment. I will put my trainer next to the 3 dead tickr HR monitors.
