this review title is: not so e z and the content is: my mom and i both received these as gifts it does not stay put and can actually throw you off balance when it goes sliding the actual product for both of ours is also different from the pic on the box ours both have very long firm bristles top and bottom that are difficult to move back and forth through and there are bristles completely surrounding the pumice stone so that you cannot really get to it the pic on the box and the advertisements show no bristles at the back of the shoe behind the pumice stone only in front of it so that it is actually accessible the way these are made the stone might as well not be there because you cannot use it i am not even sure it is an actual pumice stone after running my fingers over it it feels artificial and has a different texture than pumice it is a good concept and will at least take off surface dirt if you can hang on to it i actually worry about it causing seniors to fall instead of preventing it i have to think there are different models i looked online at the commercial and the plastic looks different and there are several colors plus no bristles at the back it says ez feet on the box but it looks like this may be a cheaper model than the one they push on their site and their commercials.there are other information for this review, one is this reviewer did not purchase it and the other is 1 people think this review is helpful.
