Well, let me share my experience with Kickr 2018.
I bought it three months ago and have 1.200 km on it for now. It had a slight clicking sound from the beginning, but nothing serious, so I decided to "live with it". Later (months or so) "drone" sound appeared (or I believe it's what people call drone sound). Buzzing and vibrations (I can literally feel the vibration through my bike) - some of them really strong. Very unpleasant ... appeared mostly in higher speeds (downhill + pedaling). So I didn't pedal while downhill and try to keep my speed as low as possible. Stupid and unpleasant, but can live with it. Later those vibrations came even in lower speeds ... let's say above 20km/h. Sometimes, not always ... some downhills were real PIA .. even I didn't pedal, my bike was vibrating like a hell .. strong sound all around .. I'm lucky I live in my own house as can't imagine to use it in apartments
And recently, something new comes .. new sound .. "scrub" ... only when speed is really slow ... like climbing. It means I can't climb (slow speed) because of "scrub". I can't ride downhill because of "drone sound" ... SH*T ... and it becomes worse and worse every day ... this piece of crap is "dying"
Here is the example of my new "scrub" Wahoo sound ..

I regret the day I have heard Wahoo name ... and really regret the day I saw some Ytb videos with reviewers stating Wahoo is "rock solid". Don't get me wrong .. I don't blame those guys ... maybe it was rock solid, but it is NOT nowadays ... If you can, stay away from Wahoo as far as you can. Don't touch it even with long long pole ...
P.S. sorry if I'm rude, but it really pi**es me off ....
