I purchased this about two years ago, but I've only used it once, so I'm putting it up for sale. I'll also include the gel that came with it. If you're spending more time at home and can't go to the gym, or if you're looking to diet, why not give it a try? ~Product Description~ ♦ MFIP (Mid-Frequency Interval Pulse) This device simultaneously outputs the three functions of "Insert Pulse," "EMS," and "High Frequency" to efficiently introduce, exercise muscles, and activate skin cells. By outputting intermittently, it replicates the finger pressure and tapping techniques of an esthetician. ♦ RF (Radio Frequency) By warming the body from the inside, it promotes blood and lymph flow, and boosts metabolism. ♦ EMS (Electrical Muscle Stimulation) By applying a weak electrical current, it unconsciously exercises the muscles. It works on muscles that are not usually used and muscles that have weakened, providing muscle training. Strengthening the muscles increases basal metabolism, making it easier to consume energy and leading to a body that is easier to lose weight. ♦ LED (Red) Red LED (620nm ± 10nm)
