Input: This machine is the worst. I bought it and used my own beans for many years without a single problem. But when this unit dies, I'm going to switch brands. As another reviewer noted, it's extremely loud, making it virtually undetectable at low levels. Then there's no water tank - one has to pour by pouring into whatever container, then add in water. What was the maker thinking?!All that said, if you're not concerned about what you buy, go out there and buy the thing. It makes excellent coffee.
Output:
Bad review
