This mini electronic muscle stimulator massages and strengthens your abdominal muscles at one time. You can choose from a total of 15 levels of intensity. It's up to you which level you choose. This stimulator is small, soft and safe, and it guarantees targeted use. Gentle electrical impulses can reduce muscle tension, or they can activate the muscle fibre for greater muscle activity. This product also features an automatic shut-off function and a self-adhesive gel film.
