This is a great idea for being able to feed my dogs outside. I gave it 5 stars as it is a good product. But, I agree with another reviewer, that the design isn't quite right yet. The top needs to open up from the front, and not from the back. My husband is going to take the lid off and change it around to make it easier for me to fill the hopper with the dog food, without having to try to hold up the lid at the same time.
