Consistent temp with PID control. Ability to plumb in. Reasonably sized boilers
Negative Product Points
None so far, no issues encountered.
Has been a great upgrade from the silvia, and was able to get consistent results with little effort. Ability to plumb in makes it much more convenient. The boilers are big enough to have consistent temperature for 2-3 drinks in the morning without having to wait for temperature to stabilize. The steaming wand took some time to get used to, but once figured out it's very easy and reasonably quick to get microfoam. It's somewhat annoying to have to fillup the internal reservoir even if plumbed in (otherwise the alarm will sound and machine will not operate)
Chris Coffee was extremely helpful and provided all the parts necesarry to plumb into my setup (which is a split with a Y from my 1/4" clothes washer hose outlet in the kitchen)
