good product because I was surprised when I read that there were only two electrodes I wondered if it would be much effective but in the end the two are enough for me it's been a week since I practice I sports alongside the abdominal sessions but we must say what we will not build a perfect body because you still have to get involved in sport to better stay on the couch, watching TV so when I ' some people hear is criticism you give and how best to buy a belt with electrodes do you buy a pair of sneakers and go running here is my conclusion
