Who do you find more useful?
I use Rose whenever available.
What I don't like about Ernest is before I go to sleep, I like stack my dairy mill with cheese and goat cheese.
However, Ernest would throw in a butter, or worst, cream in the machine before I get a chance to fill them up myself.
I know Rose can do the same with animal feed (throwing chicken feed) but it is less impactful. I rarely run out of feed as I do with dairy products.
