Are all Contour boxes bug filled trash?

I'm on my 5th Contour box since "upgrading" 2 months ago. I finally have one that sort of works, but it still doesn't work correctly all of the time. I can't believe my luck is so bad that I got the only 5 defective boxes. I would try to trade this one in, but based on the previous 4 boxes, I fear only slightly broken might be as good as it gets.
