Familiarity: I've put it through the wringer
Have had it for more than a year and it has had no issues. I got it over the more expensive Neo that is supposedly quieter and can simulate tougher gradients. The Flux is rock stable even when sprinting, although I am not Sagan... It makes almost no noise. It is also Campy compatible, as some of my friends have complained that their Wahoo Kickr's were finicky/noisy with Campy cassettes and didn't shift well. I used a worn cassette, did not replace my chain and can't say I have noticed any shifting problems. There have been ZERO mechanical or connection issues with Zwift. Power calculation seems accurate enough.
One downside is it only simulates gradients up to 10%. The more expensive Neo goes to 20%. The Neo also simulates cobbles and gravel while this trainer makes no attempt at such gimickery. It is heavy and doesn't fold up as other reviewers have stated, but that it why it is stable.
The trainer is sold worldwide, so if used in 220V countries just a different power cord is needed, which Tacx sells online I believe. I have not used the Tacx online training software.
