Hello guys I have a rMBP 15" and have been using a keyboard cover so far. However, I recently bought a radtech Screensavrz to use as well to prevent key marks on the screen. My question is do you guys think there will be any problem using the two of these things together? The fit between the screen lid and bottom case is obviously tighter now using both products together so I didn't know it this could potentially cause any harm. Thanks!
