I have the same, never had any issues with it hardware wise and I've had it for ~3 years.
I bought a Deathadder about 6 months to a year after I bought the keyboard, and the mouse scroll wheel broke 6 months ago :\ I couldn't find any other mice I like for the same price so I bought another one.
Oh, and before the Deathadder, I had a Naga Epic for a month or two, it was terrible (I returned it).
