After 2 defective Smartvent, I have again purchased a Smartvent after years due to the same dimensions. Processing is good, noises are low and the possibility to use the Smartvent over the built-in battery also at night make the obviously improved fan an interesting purchase

Priced a bit high but very clean and well done. I glued it and didn't want to drill any holes in the aluminum. Let's see how long the battery lasts. Fan is very quiet, not to say inaudible.

top quality
After almost 20 years on the roof of my motorhome, I had to install a new one.
same model, identical dimensions and therefore a 100% exchange.
That's how it's fun
