Review on OSkool AutoVac Accessory: A Smart Solution for Automatic Vacuuming by George Bell

I wanted to install a microwave in an unventilated cabinet and wanted the fan to run only when the microwave was in use. I had a fantasy that someone built this particular thing, and then I kind of laughed at myself for thinking about it. But here it is! I got the gist of the application it was intended for; not much different from my use. This works great and completely solved my problem. I didn't even have to do anything, I just put everything together. (Don't let the term "vacuum switch" fool you. It's not something that senses airflow and starts the engine like some HVAC units work with a "sail switch".) It's just the manufacturer portraying it with a table saw duster, but judging by my use and that of other reviewers, it's good for more than that.)
