Have any of you guys been using a control unit cover (when it's mounted on the shaft)?-----If so, what do you think of it and can you see the screen ok (thru the plastic window) when using it? Is there a glare on the cover plastic window (from sunlight) at times?------I applied a Z A G G screen cover on the Deus screen but would like to protect the buttons & box itself also---trying to figure out how best to do it.----------Thanks, Del
