These coffee machines are amazing. We had one in our office and it worked like a charm. I'm not an expert on espressos, but from what I do know I thought the quality was great. The self-cleaning feature seemed to work well too which is always a good thing.
I wish they sent us replacement tubes that connect the milk canister to the machine. They were hard to clean, and if we forgot to empty the canister each night, it was not a pleasant experiencing cleaning the day old milk the next morning. The hose was virtually impossible.
