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.
I was using this for my rabbits and sometimes it would just not refill so it was unreliable. I had to use the 'food dispensing side' instead and it is really hard to refill or to put back into the cage without getting water everywhere. It works this way but it is annoying, at least they can't knock it over I guess, and it does hold enough water for one day but I wish I had gotten one that refills at the top instead.
