Incredible Machine and Fantastic Purchase Experience
This thing is a tank, the performance is incredible and it’s extremely user friendly. Plus is super quiet, which is perfect for those early mornings before the rest of the house is up and awake. Online order process and shipping was quick and seamless. Cannot recommend the Mignon and buying from Chris’ enough!

Amazingly Quiet
Does a great job and super quiet. Since I have only been using it for a week it's a bit soon to tell how it will hold up. So far I am impressed with the build quality though the holder for the dosing cup is a bit wonky.
