I had surgery on my foot a few weeks ago and am starting to have atrophy in my right calf.  I saw this unit and thought it might help out in keeping my calf muscle.  I used the unit for the first time yesterday and thought it worked great.  I put everything back in the box and pulled out the unit to use again today.  What I discovered is that the plastic casing that goes around the part of the cables you plug in had broken off two of the cables.  I am using the other two cables and love the unit and the different settings.  I just wish the cables were made better.  I will be packing this up and sending it back to the manufacturer.
