Scam - save your money - just eat sensibly & exercise.
"Muscle stimulators are a legitimate medical device approved for certain conditions -- to relax muscle spasms, increase blood circulation, prevent blood clots, and rehabilitate muscle function after a stroke. But many health spas and figure salons claim that muscle stimulators can remove wrinkles, perform face lifts, reduce breast size, reduce a "beer belly," and remove cellulite. Iontophoresis devices are prescription devices that use direct electric current to introduce ions of soluble salts (i.e., medications) into body tissues for therapeutic or diagnostic purposes. The only approved use is for diagnosing cystic fibrosis.
The FDA considers promotion of muscle stimulators or iontophoresis devices for any type of body shaping or contouring to be fraudulent [3,4]. The most infamous of these devices, the Relax-A-Cizor, was claimed to reduce girth by delivering electric shocks to the muscles. More than 400,000 units were sold for $200 to $400 each before the FDA obtained an injunction in 1970 to stop its sale. At the trial, 40 witnesses testified that they had been injured while using the machine. The judge concluded that the device could cause miscarriages and aggravate many preexisting medical conditions, including hernias, ulcers, varicose veins, and epilepsy."
