The biggest assholes, unfortunately, are managing Xrite. They will not stand behind their products they deem to be "consumer". This includes the i1 Display Pro (it's "Pro" apparently only for a year) and the i1 Studio spectro. They simply refuse to repair them out of warranty, even at a cost. They also will not provide the user with easy to replace parts. Take this from a guy that had to junk a i1 DP slightly out of warranty that had been treated as well as humanly possible because of a short in the USB cable. So, there's that to think about.
