I tried a search here and couldn't find a thing about the EZ-Breeze vents by Fantastic Vent. I even tried a Google search on rv.net.
Anyhow, has anyone used one of those new EZ-Breeze vents? They look like a great solution for keeping rain out without a cover. One concern is they only have about one third the CFM of a standard Fantastic Vent. My second concern is the cost. They are so inexpensive that I wonder if they are cheaply made?
