I ordered this product awhile ago and finally got it set up a couple of weeks ago. I really like the size of this feeder. It is really compact so it fits almost anywhere! It is easy to program and easy to fill. The tray that the food is dispensed into fits into the feeder well so food is not lost off the sides or between the feeder and the tray. This feeder works with dry and semi-moist food. So it has to be filled often, somewhere between 1 to 6 days, based on how it is programmed. My only issue is i wish it had the option of a power cord instead of just batteries. However the batteries are supposed to last 9 months so it not really that big of deal.
