Review title is no rough heels for me from now on! [SEP] This foot file seems to be well made and feels comfortable in your hand while using and can be used for a long time and not become uncomfortable while using. It comes with an extra roller, which is nice if you want to share with your spouse. It is rechargeable, but the fact that is in only rechargeable through a USB makes it a little more inconvenient for me and a lot of older folks that you might like to purchase for may not even own a computer. I would much rather it plug into an outlet.This brings my opinion down to 4 stars. I personally will use my android phone charger to charge mine. I fully charge the unit for 10 hours as recommended and then set out to work on these little country girl heels that are always rough and cracked from going barefoot. I turned it on and set the safety lock and went to work smoothing my rough heels. I found that using a quick side to side motion, instead of forward and backward like I thought I should do, worked great. It was a little time consuming but it does work just as described. And if you did this as part of your regular beauty routine, it would keep your feet in fantastic shape and would not take but a few minutes for each foot. I managed to get my heels in good shape and applied lotion when I was finished and was very satisfied with the results. I think now it will be easy to keep them in good shape with this little tool. When you are done using you can simply rinse under running water to clean. There is also a brush included to use for cleaning. The head pops off easily by pushing the button on the side so that you can clean that area. I received the foot filer at a special price to try out and give my honest opinion on its performance. I think it does an excellent job if you do it as directed and don't try to press down too hard. Just use a back and forth motion and repeat until you get the softness you are looking for.
