This feeder is a good product and much better than the feeders that I have tried in other brands. The motor is quiet and the construction is durable. It is a little bit of a challenge to get the lid open the first few times you try but after that it is easy. However our cat sitter has never learned how to master the thing and leaves the lid off and feeds by filling one tray at a time when we are away. I would recommend this feeder to anyone.
