I finally got around to doing this on my DS and although pricey, I would encourage anybody with slow windows (in my case, only during winter), wind noise or a window that rattles to bite the bullet and slap one in. Took about 10 minutes start to finish and was much easier than some have mentioned (I wore mechanics gloves for a good grip which helped a lot when shoving the new run down the door).
So much nicer on the highway now. YMMV on whether or not it fixes a loose window that rattles. It did in my case. Window rolls up in a little under 4 seconds now whereas before, well, I had to help it up during cold weather. I can now approach any drive-thru with complete confidence.
