Turned of A/C & vent fans before install to reduce floating dust particles. Cleaned screen as best as possible before using wet & dry wipes included w/product. Achieved near perfect install. Width is precise. Height is ever so slightly smaller.
Note: If you wear polarized sunglasses, you can expect a slight rainbow effect that is common with polarized lenses when viewing thru this screen. Not an issue for me, but some might take issue.
