The Elitone device allows comfortable, convenient, and non-invasive treatment of stress urinary incontinence by delivering electrical muscle stimulation to the pelvic floor muscles and surrounding tissues. This full kit includes: 1 controller, Gel pad cable, USB charging cable, belt clip, storage case, 4 unopened packages of reusable gel pads (20 pads total), no manual. I purchased and used this thinking I was suffering from stress incontinence, only to be diagnosed with Dysautonomia which treatment by this device does not help. Feel free to visit the Elitone website for full information on this product.
