The windows are just ok. We have both the 200 and the 7800 series. (200 did not make the double pass thru that we wanted in the kitchen.) The 7800 are suppose to be better, but I do not care for the locks. I like the locks on the 200 series better. My biggest complaint is the color. Even though they say they are white, they are not a true bright white. From outside they look real nice and I love the the look. When the trim was finished on the inside, the vinyl trim is a bright white and it looks a little off next to the "dull" window frame. But in all fairness, you get what you pay for. We went with the cheaper window, saved $$ and are happy, but not thrilled. You can e-mail me directly at JFNuchols@aol.com
and I can e-mail you some pictures if you like. Hope this helps.
