Everything works as designed on this bad boy. No qualms on the quality of the hardware or the delivery of this particular model that has been refreshed.Only thing I didn't like, though makes sense, is that my 1 year, M$ hardware warranty was only about 7 months. Keep that in mind when purchasing. I was able to take it to the Microsoft Store and had it checked out just fine. There was a hiccup in the built in MIC which was more of a MS Windows issue than the Hardware. Once refreshed the Mic and selected the built in MIC, everything was fine.
