Doggy Man Automatic Pet Feeder with Instructions Purchased 3 years ago, the clock started to drift after several uses (the clock and timer screws are loose). It doesn't open on time, but opens 1 to 1.5 hours late. I think it's possible to use it by taking advantage of this. Also, it's hard to see in the photos, but the cardboard box is dirty. The food bowl itself is clean. I'll include one AA battery, so you can use it right away.
