Do the holes drilled into the window obstruct or affect the viewing area?
The holes are very small (about 1/8 in. or 3mm) in diameter and are usually made in the corners to be discreet and out of the main view-space. Each hole is covered with a transparent Micro-vent that is about half the size of a dime. Once installed, the vents are barely noticeable and in many cases are obscured by blinds or other window coverings.
