Curious about non-surgical lipo methods

Options
Hi all, a coupon deal for non-surgical cavitation lipo sessions appeared on my Groupon the other day and I am somewhat interested but would love more info on it. I have been on my journey for 4 months currently weighing 65kgs, exercising a minimum of 4 days a week and eating quite well, my problem area is defiantly the abdomen area, particularly my love handles. I'm curious has anyone here tried any type of non-surgical lipo method particularly the cavitation lipo? if so please share your thoughts.
