I have had original kickr for 2+ years. Changed my attitude toward turbo training. I was burned out after years of using a Cyclops fluid trainer which was medieval torture. Kickr plus Zwift plus Sufferfest plus TrainerRoad keeps things varied, measureable and programmatic (if desired). No mechanical issues with the Kickr. Usual gremlins interfacing with apps but nothing out of the ordinary. Bought Kickr2 week ago for a get away home. Same quality and reliability. However, it seems much harder at a given level of output. My 265 FTP wattage feels like 300+ watts on the new Kickr. A normal workout on old Kickr is an epic effort on the new one (if I can finish it!). Havent seen other people having this issue.
