I’ve owned many foot files in my time. This one is amazing! I get the worst dry, cracked heels (husband said they looked like earthquakes ?) I get terrible ingrown toenails on both big toes as well. I get tired of doing it and will go months in between. It gets to the point where the ingrowns start hurting bad and the heels get really bad. This time was about the worst it had ever gotten and summer is almost here (flip flop season), so I decided it was time for a new foot file. (I had a baby and didn’t have time for me, don’t judge me! lol) I chose this one not expecting much honestly. How pleasantly surprised I was to find how great it worked! I started with the attachment with the thicker course rings. It needed it! Trust me! It took off the big dead pieces of skin without any effort. Once I got the big pieces off I switched to the pad attachment with the pad sander discs. It comes with two different grits. I used both. When I tell you my feet are smooth… they are SMOOTH! I used the sander pads on my nails to thin them down. I plan on using the rings to do this as well. I worked the sander around my ingrown toenails and relieved about 90% of the pain. I will still need to do the whole ingrown toenails and relieved protocol but this will make that process so much easier! I truly wish I had done a before an after photo so you could all see the difference. The battery life is definitely longer than the 1.5 hours it lists. I went at my feet for over two hours easily the first time I used it. It charged up to a full charge in about 30 mins or so. This one is even better than the $20 ped egg brand one I’ve sworn by in the past. So for a fraction of the cost you get a way better filer, more pads, it lasts longer, and you don’t have to struggle to get refills through 3rd party sellers at random high prices like the ped egg one. I haven’t had it very long but it feels very durable. Not cheap and light weight. I suspect with care and cleaning it’s going to last a long time. Thank you so much to this brand for making such a great product and not over charging for it. My feet thank you, I thank you, and I know my husband thanks you! ?❤️❤️❤️❤️
