Looking to replace all my windows in the next year or so and want honest opinions (from people that own them) about the pella Rolscreens that are integrated on the double hungs.

I ask because back in 2000 my grandma built a house with Pella windows that had cool new integrated window shades between the two panes of glass. I remember her having such problems with them and wondered if the screens are tried a true yet.

Personally, I love Marvin windows the best but I like the idea of hidden screens enough to make a switch if its worth it!
