I *just* did this last week so I don’t have any real world feedback to share yet. Numerous lid closures in the middle of the night, most from heavy condensation, made this a must-try experiment for us. We far prefer the open windows to using A/C, and I searched and settled on the MaxxAir II. Installed 2 of them, and other than the gymnastics needed on the roof, it was a very easy install. I’m hoping to nearly eliminate the rain sensor induced closures. I did quickly recognize that the lid only opens about 2/3 of what it did before, but it seems like plenty to maximize air flow.
