I had trouble with my 5 compartment one getting stuck and not opening all the time. Brought it back and got another and that one was fine, but the cats didn't always eat out of it. It is kind of noisy when it turns, and one day one of the cats was eating from it and it turned and he got scared, haha. Since I was only really using 2 slots and I went back and got the 2 compartment feeder to try. They like that one a lot better, you can easily fit 2 or 3 cans in each compartment. I like that the 2 dishes come out separately to wash. There's no noise with it, just set the dial and it pops open at the time. I also liked that the lid just stays open so if they don't eat all the food, it just stays open. With the 5 compartment one, it just rotates. So if they don't eat the food from a certain slot, it rotates and they don't have access to it if they get hungry for more later.
I did still keep the 5 compartment one in case I ever get to get away for longer periods of time!! Good luck!
