I use it for my daily feedings. When you fill the chambers, you need to be careful that it doesnt spill over. Caught food between or behind the chambers will cause the food not to dump sometimes. The plus is that if one chamber doesnt dump, it doesnt necessarily mean the next one will get caught up.
I have it set to feed at 1:30 and 8:30. I get 2 weeks out of it that way. 28 chambers.
