Bests & Worsts Reviews from Amazon

I read a lot of reviews before purchasing this, and I was concerned about the number of complaints that the unit stopped working when pressing against a callous. After using it, I found that the only reason it would stop spinning was because I pressed too hard. Pressing harder against the callous isn't going to get rid of it faster. A callous is multiple layers of dead skin: it's going to take work and a little patience to get rid of it. Before my first use, I had thick callouses on my heels and on the sides of my big toes. This unit worked wonderfully to remove them. I spent about 15 minutes on each foot: considering this was my first use, that's not too bad. It's important to clean the roller after using it- otherwise, it is not as effective. The removed "flakey skin powder" builds up and sticks to the roller, which is like coarse sandpaper. You'll notice the difference in how it works when it's clean versus when its not. Major difference. When you open the package, just peel apart the plastic from the top and sides, it unsnaps pretty easily. Be sure to remove the clear plastic cap that goes over the roller head. It's easy to overlook and accidentally throw away. Take care not to tear the cardboard insert - that's your instruction manual. You may need a magnifying glass to read it though, the font is probably about a size 2 - no kidding! Read it though, or at least skim through it. Cleaning instructions are simple- the unit is NOT WATERPROOF. Remove the roller by pressing on the blue button with the arrow, pull the roller out and rinse it under warm running water. Dry with a cloth towel before replacing re-using it. Simply wipe the rest of the unit with a damp cloth. One thing to be aware of is the fine dust created when using this tool. I sat outside on my deck to do it, and I recommend using it outdoors if it's possible, otherwise, you wind up with a coating of powdery white dust / dead skin flakes all over the place. The handle is comfortable and easy to grip. My hands are on the smaller side, and I found it quite comfortable to work with. The rolling head spins pretty fast, and it's a very course surface, making it highly effective when used properly. As long as you make contact with the callus, it's working to remove it. Pressing harder against it does nothing to increase the effectiveness, in fact it slows down the roller and, as mentioned before, will cause it to stop spinning altogether. When using, it's best not to keep the roller on one spot for more than a few seconds: keep moving it around so you don't wind up burning (heat from friction) and damaging the soft skin under the calluses. You may not feel it burning while it's happening, but it will feel sore later on. Rub your feet with some good quality foot lotion afterwards. You're going to love your feet!
