Makes great coffee for about 4 months. Cheaply made product. All pipes inside are cheap plastic. Even a $25 Mr Coffee has copper water pipes in it to carry the 190 degree water but not Keurig....all plastic water lines. Heat plugs the lines up in 3 to 4 months. Piece of cheap junk made to look pretty. Save your money

Ex Output:
Negative

Positive

I use this to record in GarageBand on my MacBook. It works unfailingly and sounds as good as it should considering my primitive setup. I love the level knob and the quality construction. If you read the instructions and use it correctly, this tool is invaluable.

Positive
