The product suits my needs to a "T".  Programming instructions are not easily understood - I would suggest setting the program and confirming it functions prior to 'leaving town'.  The bin holds enough food (about 4-lbs) for 10 days feeding 2 - 1 year old cats 2 times per day.  Initially the noise of the kibble falling into metal dish frightened the cats; now the cats have a clear signal that dinner is served.
