i have one of those inexpensive timed feeders too. from the factory, it is set at 6 seconds of spin at daybreak and again at 60 minutes before nightfall. the setting and feeding times and amounts and all that other stuff can be changed (it' s much more difficult than reprogramming a windows computer). if the battery is removed, it reverts back to the original factory setting. i' ve tried several different varations, 3 seconds and 2 feed times in the morning etc., but it seems to work best with factory settings. it goes through about 40 lbs of corn in 8 days.
