I have 2, waste way too much food. Unless I modify them, they will only be used when we are on vacation. I agree, the food needs to be at least 3-4 inches beneath the lip of the feeder.
I have the Hentronix coop door for the eglu go up and I love it. I opted for the WiFi option and it was the best decision ever. I can close the door while away on vacation. It’s pricey but a solid buy.
