I used to be able to hear my feet scratching up against my sheets, but now I slide into bed like a mermaid gliding through the sea.

I regularly go to town on my heels and the ancient callus on my big toe, which has all but disappeared since I began using it. It is essential, however, to follow up with a rich lotion to truly preserve the results of the electric foot file. I like to slather on Weleda Skin Food lotion and then tuck my toesies into a cozy pair of socks.

The device conveniently includes four AAA batteries, so it’s ready to use immediately. Just be sure to do it over the tub or a towel, because that dead skin starts to fly off immediately. It has all but eliminated the need to get pedicures, since the results of those are not as long-lasting or effective as they are with the callus remover.

“Game changer! Heavy duty and worked miracles on my dry, cracking heels that no amount of daily feet care (foot scrubbers, files, etc) and lotion could do. Even a pedicure would have limited effect compared to this. It looked like I was using a wood chipper but in reality I was doing away with all the dry skin and callouses. I wear flats and sandals often, so my feet need to be maintained if not they’re horribly dry. Easy to use and appreciate it comes with batteries. I wish I bought it sooner.” —Stephanie H.

“Does the job! Read the reviews on this and the price was right! I love how easy this is to use. It files down the calluses perfectly. Great to use in between pedi’s. I also used it on one of those dry painful cuts you get next to your nails during winter. It worked and I got instant pain relief.” —Marie

“I have a thyroid disease and naturally my feet seem to always be dry with cracked skin. I’ve tried so many different manual interventions but so happy I stumbled upon this product. I’ve only had it for a short time, but it’s so easy to use and effective! My feet were so soft after using it and I didn’t have to scrub at my feet to get them that way. The price point is reasonable in my opinion and my feet couldn’t look better!” —Amazon customer

“I cannot believe how amazing this tool works!!!! I have cracked and dry heels. I have tried every cream and lotion and wear socks to try and help them not be so dry. I decided to try this file and have NEVER had feet this soft. I would say they look the best they ever have. It helps to put lotion on afterwards. The file is nice and small but powerful. I want to buy this for everyone I know!!” —Melanie S.

“I am 70 year old and I am a diabetic. I wanted to have something to remove the hard areas on my heels/ feet even tho I go to a salon every month to get my nails trimmed. This is excellent and easy to use. I would definitely buy this again,, You just put in the batteries that it comes with and it rotates and removes the hard areas on your feet, it does not hurt and gentle to use.. I did not use a lot of pressure and in seconds my heel was clean. I like the idea that you can remove the pumice roller and clean it in soap and hot water and replace it for next time. A good gift to buy for a person that are concerned about their feet,” —Amazon customer

“Works great. Using on some calluses on my feet from running and it’s way better than a file or any other products I’ve tried. Came with batteries and took a few seconds to set up and was ready to use. Safe to use but read instructions to not over do it. Spins fast and easy to control will shut off if you press too hard so you don’t cause skin removal.” —Steve

“This really works! This callus remover is awesome. I have a fused right big toe that takes the brunt of my walking thus creating two thick calluses under my right big toe and toes 4 and 5. I used this foot file on these calluses that resulted un a much smoother foot with no pain. I love this product.” —Amazon customer
