I received it and used it immediately (after I cleaned it of course!). I was pleasantly surprised!! It grinds kind of slow, but it never got hot when I used it! And, I ground enough flour to make muffins and bread in one evening with no issues. It never even got warm. Not only that, but it made the lightest, most fluffy loaf of bread that I've ever made! It definitely makes a difference to use fresh flour. I think the problem is that people probably try to grind a bunch to save, but there's no reason to do that. You might as well buy a bag of flour at the store if you're going to do that. The point of having a grain mill is to just grind what you need that moment because the nutrients oxidize out of it very quickly! So, if all I'm doing is grinding what I need at the moment, I will have no issues.
I'm excited to finally have my grain mill. I plan to use it OFTEN! It will just stay set up on my counter :). The bread that I make now is so easy that I could make a loaf every day and it wouldn't be an issue... and at the rate that we go through homemade bread, that may be reality very soon! It tastes so yummy and provides so many nutrients.
