How many times did they have to measure the screens?
I got my new screens a few weeks ago and forgot to update here. They measured them once and sent out the screens a week or so later. The new screens are good - not perfect, but I am happy with them. One or two have tiny gaps at the top if they are pushed all the way to the bottom, but by tiny, I mean you would probably not be able to slide a piece of paper through them. And by seating the screen just a little higher, the gap dissapears.
The screens are now more difficult to get in and out because of the tight fit, but I don't expect to be removing them very often, so that is a trade off I can live with.
So overall, while the screen design could be better, I am pleased with the windows. Since I have no real life experience with other brands, I cannot compare.
