While there have been issues with the 2018 Kickr and the Kickr Core I think it’s worth noting that seeing a ton of complaints online does not indicate that many units, or even a significant percentage of units, will fail.
With something like the Kickr Core if they sold 100,000 of them in Q4 2018 and had a 1% failure rate that would mean 1000 very vocal very post heavy users complaining on facebook and on these forums. If they saw something like a 25-33% failure rate they’d be completely overwhelmed with 25000 vocal angry users.
None of this is to say that the products didn’t both have significant release problems (I had a faulty kickr core delivered to me directly from Wahoo a few months ago, they replaced it a week later) but I do think that we can end up in a bit of an echo chamber on these things where the only people posting are those who had an issue while the (vast?) majority of users had no issues and as such don’t need to even check whether such a complaint venue exists.
So…honestly, I’d be perfectly fine recommending a 2018 Kickr or a Kickr Core to someone right now, it’s a fine product and they handled the broken one I got from them quickly and without any cost to me.
Not to say there aren’t other options that might be every bit as good - the smart trainer market is in a fantastic spot right now - there are tons of great options - just that if you have looked at everything and the Kickr Core sounds like it matches your needs I would recommend getting one
Honestly - more of a commentary on the state of internet complaints than anything else. Not intended to be a ringing endorsement or criticism of Wahoo
