EXCELLENT DEVICE.  HIGHLY RECOMMEND
I purchased this for my sister for Christmas who has a terrible condition of very very rough feet and hands.  She is also difficult to buy for because she always says she doesn't need anything.  She is over the top elated with this gift.  I also bought her a 12 pack of the green extra coarse rollers and she is absolutely ecstatic over this gift, which pleases me to no end.  I have this item for myself just to maintain my pedicures and I love this item.  I prefer the plug in which this is as opposed to the battery operated model as the speed at which this runs, really goes through batteries.  I also have the battery operated one which I bought before I knew they had the wired one.
