The machine worked beautifully, but I'm not willing to ingest the plastic residue tainting the water. It's disguised in the espresso, but when you brew just water, it's a strong taste and would seem unhealthy. This happened to me with the Starbucks machine, and was reported with Mr. Coffee also. I suspect it will be true w/all pump machines that use plastic reservoirs where it heats the plastic. I strongly recommend not buying the Walmart protection plan as they are delinquent w/refund and communication is difficult w/out of country staff.
