Do they work - yes, they send a small electric current through certain muscles dependent on where you locate the gel terminals - provided the gel terminals are kept nicely moist.
They will omit to tell you that you can keep the gel terminals moist by just adding a few drops of tapwater before you put them away each time. They would much rather sell you nice new gel pads every few weeks.
but I feel your question is, do they make a person look slimmer?
I have never known them make a difference.
