I love keeping my feet clean & dead skin free, so i try to keep my feet smooth & keep dead skin off, bt sometimes it can be impossible. In the past i have used regular foot files, which became messy, so i wanted find better option. Then i found out about foot masks, which is okay. When i came across this electric foot callus remover i knew it would help a lot. I charge it for a good 40mins before i start, cause i want it fully charged. I make sure my feet are clean. Comes with 2 roller heads & speed settings. After use the grinding heads can get cleaned, so thats good. Has powerful speed suction with built in vacuum. It does the job. After all cleaned & done i put cream on my feet & they look so smooth, so nice. Few things wasnt happy about. It comes with a usb cord, bt i wish cord was longer. At 1st when i receiced it the protective case underneath was cracked/scratched & a piece was missing, so i had to replace it & the reason for 4 stars. When i received 2nd one the protective case was still scratched, bt wasnt as bad & all pieces were there. Great product tho that works.
