I wanted to get away from plastic, and was looking for stainless steel. I wanted something washable, but also non-slip. These bowls (I bought several colors and 2 sizes) have removable rubber rings on the bottom so they don't dry out in the dishwasher. So far, my kitties seem to like these better than some of the other bowls we have around the house, so that is good. The price is more reasonable than a lot of other brands. We've only been using them 3 or 4 weeks, but so far so good. We'll see if they stand up to the test of time. I like the 2 sizes I got, and kicked myself for not ordering one more when I placed my last order. But so far, I like them.
