Summary: I have purchased 2 of these - Only ONE experienced a failure and that is because a calcium particle got into he fine tubing of the espresso portion. I recommend the filters on at least the espresso side - they will prevent this issue (drip coffee side doesn't use pumps - std.
Summary: I researched and read almost all reviews on almost all machines. All the negative ones scared me off! Finally, I was fed up and purchased this machine at BBandBeyond for $299 (minus 20% w/ coupon).
