My brother installed 7 American Craftsman windows for me. He did a great job but we've had some issues with a few of the windows. 2 of them seem very loose. One of the 2 won't stay up at all on it's own. The windows have tabs on them that you can pop out and it only allows the window to go up so far. Its a great feature, especially for windows at a level where someone could just open the screen and enter the house easily. The problem is that these tabs have a plastic piece around them and within one day, the plastic piece came loose and now it stops the window from going up. It's not like I can just take the window out and return it. They have been framed from the outside so they are in. We just have to live with the defects I guess. So I wouldn't really recommend these windows. Too many issues with them. Check them out good before you install them.
