every review i've read of most of the massage cushions say they don't work or just vibrate & the massage isn't deep enough or that the machine just vibrates so much it just shakes u up & flips u out(is uncomfortable) anyway its my girls b-day & she has scoliosis & i have to fucking massage her day in & day out. & i suck at massaging. my hands r like to wooden blocks without fingers & i don't have any coordination. if there is some kind of machine out there that will massage her for me, please help me. my price range is like 100 - 200 bucks but if anything works feel free to talk about it
