Buy It It's Great
I have some seriously heavily callused feet, I watched all the video demo's of the other popular units I could buy locally which are all battery powered. Not everyone would state that the battery operated units bog down if any pressure is put on them but a couple did, and there are very few demo's on this unit but the one I did see said it 'didnt bog down' and I can tell you, unless you push down enough to where you may likely hurt yourself, this unit does not bog down, it's great.
