"Of the three feeders I purchased, this was by far the worst even though is was NOT CHEAP! Very hard to fill the 14 very small feeding compartments. Since there is no bottom to the tray it must be set on the feeder before filling. In case you spill some feed (and you always will with this set up) the feed falls into the timing wheels. Of course you can't pick the tray up to clean because it has no bottom. Extremely poor design. Stay away from this one even if it is for free!!!!!!!!!!!!"
