I bought this so food can reliably be dispensed if I am held up at work.  Family is out of town so there is no backup.  Set up the schedule and worked for two days.  Then it started to give varying amounts of food out instead of the consistent amount programmed.  After that it stopped dispensing altogether.  Lost the manual so could program the clock and schedule but never get it to re-engage to dispense on schedule.  Not happy that this does not work reliably.  The controls are also easy to bump or put hands on it when lifting causing it to go back into program mode.
