This one is simple, almost as easy as pour-over, and is simple to clean. We're making better coffee at home than we've ever had in a coffee shop. And I thought it would take a while to dial in, but the first shots were great and they've only gotten better.
It's a little spendy, but if you buy espresso-based drinks it pays for itself in no time.
