I have mixed feelings about these windows. They achieved the look I was after BUT they are certainly not functional. They don't seal worth a damn which means a lot of wind noise, you can't roll them while the truck is moving (wind sucks them outward), and the corner piece fitment is garbage. NO WAY would I recommend these for a daily driver!
The loss of functionality for me was not that important. My trucks hibernates during the winter and does shows/weekend cruises during the summer. So if you like the look, go for it. Just don't roll them up!
