Travel Trac Inertial trainer?

Performance bike had this trainer on sale, and I am wondering how quiet it is?? I live in an apartment and my old wind trainer annoys my neighbors.

That model is made by Blackburn. SUPER quiet. Quieter and smoother than fluid.

Hmmm....

must be something new.

Fluid units are the quietest, fans the loudest, magnetic somewhere in between. Don't know how inertial fits in there. One would hope that it would be quieter still....
