Query: I just don't get it

I bought these based on the reviews but let me tell you that these suck big time. I am a dude and I bought these for my wife because she needed one. She said they sucked so I tried them out myself just in case she was wrong. Nope, they really do suck. I have rough feet because I am a dude and I was expecting my feet to be like a baby's butt after using the smoother. They still felt like sandpaper. This is how I did it. I went and showered, waited a few minutes for my feet to soak up the water, then I started using this smoother. Nothing. Just crap. What a let down. I was planning on playing footsies with my wife without cutting her.
