I bought the Zagg shield for my 7D and ended up returning it - the protector for the top LCD was about 0.5 mm too wide, and it extended off the clear plastic and over the seam onto the black part of the case, meaning the fit wasn't flush. Having said that, the product itself is nice - I have them on both of my daughters' iPads, and they work quite well. I might try one for the 1D X when I get it...
