Took me a bit to get the lead to stay in at first, it kept turning off, had to really shove it in to work, I leave it in permanently and just plug in when needed, really works well on the skin, ive had this treatment at a salon so I known to keep moving sometimes slow sometimes quicker working across the body, its improved my skin tightness loads, I do it 5 days a week, it does take a good 3 months and you must be dedicated, I do it before bed, its so worth it, commitment equals results. Im in my late 40's, worth every penny for me.
