Has anyone tried the Plastimo battery powered solar vents? These seem to be very similar to the Nicro day/night vents, but cost a bunch more. They are only 2 inches high which is nice, but at roughly $350 a pop, I have to wonder if they are made of gold?
The other advantage of them, which is why I was looking, is that they are a tings smaller in diameter than the Nicro...
