Where do you store the remote when not in use? Mine had the button array break and MK sent me a new one for the swap...this was a known problem with a batch of button arrays..bout 5 minutes to replace and 2 days to receive. Other than that, I've been running mine since about April with no other issues. Course, I'm lucky to average 8 hours a month.

Still, my remote would look like new if I wiped it off. I'm guessing yours may be getting UV damage from constant exposure combined with wear.
Regardless.....I'm confident MK will fix you up.
