I bought this about a month ago, I was tired of the bathtub drain being clogged. I saw the TubShroom and could see the benefits right away. It is made of a silicone material so even if you run into it with your toes you will not get hurt. There are holes on top and all over the cylinder shape which allows the water to flow, but the small holes and little feet catch the hair at the bottom. After a few days of showers I removed the TubShroom to see if it was doing what it was supposed to do and yuck the amount of hair it had collected. I took a paper towel and cleaned the hair off then rinsed it with water. Back in it went and I am happy to say no more clogged drain. When installing it took just a few minutes because I had to remove the metal drain cover and the screw was stubborn.  I need these in all my drains now.
