The conveyor belt and 1/8 ounce buckets is the best design I've seen for an automatic pet feeder, I've had this over a year now and still working, with no jams and still dispensing the proper amount of food
There is one thing that bugges me a little bit, the clock runs slow (about 15 minutes in a couple of months) and I have to reset every 2 or 3 months
Sorry only gave it a good rating due to the clock issue
