Not well made
I bought this in October. I only took it out of the box recently, within the last 2 weeks. The part that plugs in to the surface pro is coming apart like it wasn't glued shut correctly. I am so unhappy with this purchase. My original AC adapter lasted for 5 years, this one lasted 2 weeks. Absolutely DO NOT buy this! Waste of money! Well, this was purchased in October 2018. By January 2019 the entire thing has fallen apart and no longer works. Absolutely terrible product.
