Good for vacation
I used this device for a vacation where I would have infrequent cat sitters. It was easy to assemble and moderately easy to program. For cats and small kibble, I found it fascinating that i needed to schedule mere seconds to get the correct quantity. The only issue for my cats is that one of them dominates the other. They are accustomed to separate bowls, and even though this bowl is big, one tends to chase the other off because now they must share. Not a defect of the product, just the reality of my cats' personalities.
