My D1 starting wigging out on me and I have the warranty so they sent me another D1. About four days later the "like-new" D1 (more accurate term would be like-crap) started doing the same thing. Spent 25min on the phone with an associate and then asked for a manager. Spent 2min with him and should have a D2 today! Moral of the story, go straight to the top. I honestly can't wait to root this bad boy.
