Query: Disappointed

"Be Warned" Yes this is a clever idea at first glance. Unfortunately the product does not work efficiently and the company does not back up their product return. Due to the large quantity of food coming out at one time the company advised that we take the dispenser apart and move the dial to a desired setting (why isn't this in the instructions? wait...there are no instructions). They said we could return the dispenser if we still had problems but would first need to call. We tried their suggestion and unfortunately same result. We made numerous calls about a return and were told each time that they had to check with the supervisor and would get back to us. Still waiting. . . Anyway, will be passing it along to someone else who allows their pet to eat large amounts of food all day. By the way, any cat who eats all day will have major gastrointestinal problems! What a mess!
