Review on Mini DisplayPort to VGA HDMI DVI Adapter for Surface Pro, MacBook, and Surface Book - Connect to Projector or Monitor! by Wendy Williams

Works great. It's fast and works better than my old one. I didn't test the HDMI output but I used it for DVI and also tested the VGA connection to make sure they both work (I'm using DVI). I use it to connect my surfacebook to an external display and extend my desktop. Works perfectly and had no problems with it. And this one seems to be MUCH more durable than the old key and I love that I can just carry it around with me instead of lugging around tons of little adapter cables or playing the lottery and guessing which cables the customer will have. Good product!
