I’ve understood some people have had some minor issues with it, but for me it’s been pretty much perfect.

@caseyliss just wanted to share an update on the European power-brick noise issue that I shared with you a while ago. They finally shipped out replacement units after one year of waiting. Zero noise in my case, however their support email mentioned that some of the newer bricks were not fully silent.

Not sure if existing stock has new or old power-bricks.
