To hard, slips and slides because suction cups fell off one by one first day of use, pumice stone broke in half third use. Crap product.I'm martial arts instructor and walk around barefoot about 95% of my time. My feet take a serious beating and I've been looking for something that will scrub away the considerable dirt that accumulates after training and teaching for 8 hours a day, 6 days a week. Then I found this and I'm very happy with it. It does a great job and the description of the item is quite accurate. I can see room for improvement in the design:1) I wish the top part was made of something softer and a bit pliable. I keep slamming pinkie toe on it when I use it and that's no good.2) I wish it was a little easier to move around, once those suction cups are down, it ain't moving so easy!3) I wish the pumice was just a hair bigger and maybe along the side instead of the heel. I have to turn my leg a funky position to use it properly.4) I wish you could load soap in it somehow, instead of pouring liquid soap on it since the soap tends to drip through the drain holes on the bottom.But honestly, these things I mention are just inconveniences that a more thoughtful design would fix. But over all, I would buy this again because it does work like it says it does and it's super cute to see this giant blue sandal-looking thing on my shower floor! Also, as a female instructor, it's especially important for my feet to look presentable since women in this field tend to be judged on appearance a little harder than the men. We need to be able to kick butt AND look good, this little guy helps my feet stay pretty in between pedicures ... and sparring matches.Only used once so I'm still deciding on this purchaseJust received item and have only used it once. Can't really comment on durability, but hoping it lasts quite a while. I do like the product.RETURNED!First of all, I am barefoot all day long, so I need to clean the bottoms of my feet, but I also do a lot of dying, and constantly have dye spraying or dripping on the tops of my feet as well. So when I get in the shower, I usually end up scrubbing my feet with a brush anyway - I thought this would be great, because it scrubs the bottoms *and* tops at the same time! Yay! What a great idea!.... NOT.Problems;1. First problem, the suction cups suck (and not in the way they should!) The thing slides around, and is nearly impossible to keep still long enough to get on a good scrub. I spent more time chasing it around the shower with my foot, than it would ever have taken me to just scrub my feet by hand. Even when I was able to keep it still long enough to start scrubbing, every time I pushed my foot into it with enough pressure to actually scrub, it started to move again, and here I am chasing it around the shower again! So #1, bad suction.2. And this is the worst part! When I was able to push it up against the side of the shower so it wouldn't slide around so much, I don't know if it's because I have high arches or what, but when I put my foot all the way in, that hard blue plastic across the top just scraped the tops of my feet raw! Very painful, and even feeling kind of bruised as well!!So even if it didn't slide around, and make it impossible to scrub for more than 5 seconds, it is so painful to put my foot all the way in, so I wasn't able to scrub the whole foot, I had to just do the bottom of my toes, and then going only up to about half of my foot, stopping once it got to the hard blue plastic on top. So after my first use, my feet remained dirty, and now have painful scratches on the tops of my feet.Not a pleasant experience to say the least!! I saw another one on here that only does the bottoms, so I am going to cross my fingers, and try that one, and hope that the suction cups work better! It won't get the tops at the same time, so it won't hurt them either!It works well but I have to hold it down with my other footUsing this product and Defense Shower Gel (link here: https://www.amazon.com/dp/B01BICMJ16/ref=twister_B01E0GSW8Q?_encoding=UTF8&psc=1 ) I have been able to completely get rid of Athletes Foot (after having Athletes foot for 6 years). The defense soap is the cure, this thing just makes it easy to use it every day. I mix one bottle of defense gel up with water in a spray bottle which I spray onto my feet and then scrub with this thing.The main complaint I have with this item is that the top part hits me on the top of my foot even when trying to be careful not to, and it hurts pretty bad when it does. If the top part (the arch holding the bristles above the foot) was at an angle, the edge wouldn't hit your foot and it would make the whole thing allot easier/comfortable to use. The only other (minor) change that I would like is for it to have more bristles in the back instead of the stone and the bristles in general could be a bit firmer as they are very soft.Overall it's a nice inexpensive product that works great for me.Let me start with admitting my biases: 1) I read all the bad reviews, so I had extremely low expectations, 2) I have huge feet (size 14). I contrasted it and compared it with similar products, but this was the only one I could find that could do the main things I wanted: A) Get between my toes (hard to do even by hand!) and B) Get the tops of my feet, too. All the other products I saw only got the bottom of the feet. Found it on sale for $7 and free shipping when I added it to another order, so I figured I'd give it a try. Been using it for a couple weeks now, and I love it! Yes, it does slide a little, but not much if you use common sense (and have a large foot); you're not supposed to put your weight this, you put your weight on your back foot and slide the other one in to wash it. It scrubs my feet great and better than I could do it by hand. Now I said scrub, which I need, but someone with more sensitive feet may find it a little harsh. No more toe jam! And the bonus? Due to the pumice stone, the 20-year-old callouses on my heels were gone within a week or two! I'm so glad I got this, it was definitely a bargain, but maybe I don't expect that much for $7.Strong bristles, great for cleaning feet. The only thing is the suction cups slip and come apart sometimes. I'm still happy I bought it though. It feels great on my feet.
