Review title is helps my heals with the dry skin [SEP] This is a great machine. It really helps my heals. I wear sandals almost year round so my heals are really exposed to the dry air a lot. I wish it were a little less expensive for replacement files but other than that its a good machine and helpful. The battery seems to run down fast and it really needs to be plugged in for it to work well. If its not plugged in it seems to keep stopping if any pressure is applied to the file. I've never had a different brand so I have nothing to compare this to.
