I had the chance to put these on a house I built. I ended up not doing it and using a more standard type. I slightly regret not having them in a few of my window use cases BUT, at least the ones I saw, felt very flimsy and rattled/slammed a lot.

Another challenge for this type of window: it's challenging to hook up a portable AC unit in an aesthetically. This is a factor if you don't have central air and need to retrofit cooling.
