Query: Tricky but once you get it, you will love it too!

I have tried it in both ways. Wet and dry. I still prefer it dry because I know where to go and not to cut myself.It does exactly what it says. It is easy to use once you understand it and if you remove the blade, just take your time to put it back. Don't blame the product if you can't do it. It might cut you if you're not doing it properly, but it's like any other tool, you just need to learn how to do it. Do not use it on good skin, just on those horrible callus! If not, you will cut. Do not try to remove it all in one day, it takes time. I have used it one time per week for a month, 2 months ago and I don't think I will need it until later.My recommendation is use it at night, before going to bed, do all your stuff and then put some nivea cream or other cream and go to bed, do not walk after it so you can have a nice result. And also, if you feel pain the next day, it's probably because you went too deep. Just get better the next time!
