I've always kneaded dough by hand but really don't ever do it enough.

I've never owned a Kitchenaid mixer or a bread machine and I don't see
how that dough hook attachment can actually knead dough.

But then, I've never seen one in action.

Does it really work? How about bread machines? And how do they
compare?

What are my options for "automatic" dough kneading?

Thanks.
