I prefer the simple operation of the traditional fantastic fan. KISS
The rain sensing fan handle needs to be pulled down to operate manually. My experience is when the handle is pulled, the auto closing function takes over, which I find frustrating. The auto fan feature is noisey, will wake you up at night if automatically closing.
If I am gone during the day I leave the fan slightly open. About 50% of the time the teardrop is covered with an awning anyway, so not so worried about rain.
