Works very well.
Just started using this electric model.  I like it better than the battery version.  Just start slow with electric version if you are new to it until you get used to it. I tried to use it far too many minutes at one time in the beginning and I ended up with some slightly tender areas on my feet.  It works, to me, faster than the battery version so start slowly (a little bit at a time until you get used to it).  Also I do not have to worry about loss of power as I did with the battery version.
