I got three hooked up and wouldn’t fly without it. Really adds to the immersion. One is not good enough and will only give you a taste. You need additional software if you want all the effects like gear,flaps, takeoff and landing roll, and turbulence. I only use the buttkicker on the chair the other two are Aurasound AST-2B-4 Pro Bass Shaker Tactile Transducers attached to my desk. You will need amps and a sound card for each transducer. Once you get it all set up yo will see what you have been missing in the sim experience. Josh
