I really wanted to like this feeder, but I don't. The main problem is that you can't program it, you can only set it to go off EXACTLY 6/12/24 hours from the time you turn it on. So if you want to feed your cat at 6am, you better be around at 6pm or midnight to enable it. If you don't use this every day and always have it turned on, this becomes a major hassle.
