Works well. I have used this prettySmarty abs stimulator , these pads go on the abs stimulator . It strengthens my abdominal muscles. The hydrogel pads long.
These hydrogel pads are awesome It was life changing for me using prettysmarty abs stimulator after I had my son. I worked out a ton before he was born and continued after he was born. But I couldn't get my abs back. My stomach felt like JELLO. So my husband got me the prettysmarty abs stimulator. I was scared to wear it at first, I thought it might shock me. But I gave it a shot and ended up loving it. 2 weeks later I could feel muscles in my stomach again.. I have always used it for 30 mins at least 6 times a week. I even take it on vacations :) Best money I have ever spent!!!!!!
