I would actually without these so-called ButtKicker no longer sit at the flight simulator. On chair bolted this device Transfers the Motorgeraeusche, adjustment of the flaps and / lowering the landing gear vibrations to the body, followed by setting a higher Realitaetsgefuehl of flying. The intensity is individually adjustable. One disadvantage I feel the loud noise of the fan. The vibration CONFERS Also unfortunately through ceilings and so I would advise against the purchase if you have a lodger! I use the football as an instrument at the "fly" while the loud fan noise goes anyway under almost. The products seem well made and I expect many years of gaming fun with it. That's why I forgive 4 stars.
