I bought this for my son, who is a video editor. He is thrilled with it. He compiled a video on his older Macbook and it took a little more than 10 minutes. Same video on this new laptop took just over 1 minute.  When we received this, the wall charger was not working. Doubledex reached out to me, suggested some troubleshooting, and then shipped us a new charger within 2 days!
