The feeder is extremely easy to use. It came already put together. The seperation insert and lid come out for easy wiping out. It is very user friendly and easy to set up. The digital display is easy to read. And I love that it runs on batteries. It can feed up to 6 meals at intervals of up to every 15 minutes. However, I use it to just feed once a day in the evening for my outside cat. It makes it easy to feed her in the dark and cold months. The only cons that I have found with the product is that I have not found a way for the actual food tray to come out so that I have to carry the whole feeder inside to refill it. I also don't like that it only holds 6 meals. In my opinion, holding a 7th meal so that it can be refilled on the same day every week would be much easier to remember.
