For what it’s worth, I have none of those trainers.
After some agonising research, I have bought a Bkool Smart Trainer and it is not having any of the aforementioned traits/issues.
It is half the price of a Kickr but a bit more than the Vortex (if I remember correctly).
Yes, the bike will need to sit on the roller and will have some tyre wear but I have now ridden 3500 km and reckon i will do easily another 2500 km before tyre change. I see this as not a problem.
I have it in a little room with the wife next door and there is no problem with noise as it is really the quietest i have heard in comparisons. I don’t even have to close the door. (… and no, she is not deaf).
There is no need for calibration, spin down at all.
It is a very solid construction that also folds down if not in use.
It also gives the bike a bit of movement and give rather than being unnaturally stiff. This feels a lot better when sprinting or up-hill out-of-saddle action.
No need to ever adjust roller tension as the Bkool works on rider weight to press on the rollers. No problems when out-of-saddle as bike will not come back up on its own.
Plug in, connect and swift off.
Sofar, after 3500km not a single problem at all. Very happy.
