Easy to tip open, hard to fill, dispenses unevenly.
For the price, it's okay but there are a lot of drawbacks. First, it's very easy for the animal to tip up the top part, (deliberately to get at food/for fun because cat do that sort of thing/because it's just too loose). Secondly, bigger food doesn't fall through the hole easily as there's no real slope, you need very, very small food. Thirdly, it's next to impossible to fill with water. At most you can get it 1/3 full. Using icecubes and topping off with water helps a little.
