Before I write this review, I tried it for two weeks in different modes. I use it for 30 minutes every day on my belly, and I can feel a little current when I use it. I feel my belly skin is firmer than before after two weeks. LOSE 6lbs within 2 weeks, I can not belive that !! I think I need to wait more time for obvious changes. I recommend it 100% to those who have similar problem as me
