I purchased this feeder after my cat broke the LeBistro brand feeder I had by repeatedly sticking her paw up into the food dispenser to coax more kibbles out. The design of this feeder prevented that, but it was clunky in other ways. I had to remember to fill it again every few days by guessing when I had last done so, because you cannot see which of the hidden trays are empty. Since I could not figure out how to lift the tray cover, I had to rotate it by battery power - very slowly - tray by tray - to refill each one. The batteries lasted several months, but when they began to run down, I could not for the life of me get the center console with the motor in it to "lift" out (as per instructions) to put in new batteries. I pried it with a screwdriver, rotated the cover to each tray in turn, shook it - nothing worked. After two frustrating days, I finally sent it back to Amazon with the dead batteries still installed. It was useless. I would not buy this model again.
