It does its job, but it makes noise like a clock and has a delay in opening of about 15-20 minutes.... Overall, for its price, it is quite decent... It does not have an ice compartment

The problem is that the sound of seconds (click-clack) can be annoying to some people.
Another disadvantage is that the cat smells the food inside the container and starts pushing, pulling it with its claws and generally pushing it. This means that it may get stuck under a couch or a counter and the device may get trapped there, resulting in not being able to open the lid!

It can be adjusted for up to 48 hours and works with one AA battery. I have two cats, so I got two for each cat (a total of 4 feeders) for when I'm away on weekends. I fill them up on Saturday morning before I leave and set them to open one on Saturday night and one on Sunday morning so they can eat, and I can return late Sunday afternoon or evening (I keep the cats in separate areas so that one doesn't eat the other's food). It works perfectly fine for 1-2 days if you're away. When I'm not using it, I take out the batteries so they don't run out because it works like clockwork. The package says it includes a cool pad to place under the dish to keep the wet food fresh. The ones I bought did not include it. Only time will tell how long it will last.
UPDATE 30/11/2023: It has been a lifesaver for me. I have used it many times and it works flawlessly. It opens at the set time and my cats have food. I can be at ease when I'm away on weekends.
