This product is a great buy for the money.  I shopped around a lot and couldn't find anything to compare.  This is the second one I bought.  I've had the first one almost a year and it's still working.  It is pretty quiet and the timer works well.  My cats don't try to break into it like others seem to do.  It won't work with wet food for 6 days though because the ice will not keep (since it's just water in plastic) but works well for a weekend away.  It has eliminated me having to get up at 4:30am to feed the cats too!
