As hoped. No real story here. I ordered an adapter from you. It was shipped by Post, and it got here in good time. That is always good news, albeit surprising news. Maybe our post offices have their acts together. Also the quality of the component is higher than I expected, for the price.
This is a bit of an "outside the (computer) box" solution. Order in confidence from iFixit and rely on the Postal Service.
