Recently moved into a condo with others above, below and beside me...Problem is when playing pinball I irritate the neighbors below me and they mistake the flippers clacking away as someone knocking on their door. Has anyone else ran into this problem?? I am wondering if cushion flooring such as those children's large jig saw pieces might suffice under the legs? It is the sound of the flippers themselves which are louder on Stern's then on previous Bally, Williams DE etc...Any input would be awesome !
