Bought thsi feeder, followed instructions and it did not accept a proagram for 1,2 or 3 feedings a day. Tried 4 days in a row. Returned item and received a new one with THE SAME PROBLEM!! Now I'm not a genius but I am and engineer so I should know how to follow minor directions (granted most engineers don't follow them - initially). Piece of junk! Bought a cheap feeder at the local pet store that works.
