Think Tank Hydrophobia clear LCD screen opacifying?

I've been told the plastic clear viewing cover for the camera back LCD becomes cloudy with time? Any experiences?

Also, does condensation happen along the lens, body, or the inside of the cover?

Yes, it does get clouded. I just use a bit of car polish on it once a year and it cleans/clears it up great. YMMV

Never had any problems with condensation.

Got it anyway, but returned it. The plastic wasn't the problem, it was that the Hydrophobia outrageously expensive eyepiece and it's neoprene backing obscured the upper third of the LCD. What a poor design, esp from a company that claims to be run by photographers, for photographers.
