Review on Stress-Free Potty Training With Skywin Dog Puppy Pad Holder Tray - No Spill Pee Pad Holder For Dogs - Easy To Clean And Store, Suitable For Most Training Pads (Dark Grey) by Sam Dhungana

There are reviews that mention the lip size and I noticed that when I opened it too. BUT this thing works perfect! It saves me so much time because I don't have to clean the floor anymore or underneath the pad. Best buy ever!UPDATE:These are very slippery when wet underneath. The one I have was wet underneath from when I mopped and when accidentally hit the corner of it when I was walking out of the bathroom, I went straight down I broke my elbow in two places and screwed up my back.
