Yeah if it only takes a few mins the only thing you would gain from a fogger is better coverage. But you just use a few extra mins to make sure you get it all.I got one of these recently. Ain’t automated but makes things fast, I can fog all my tents down in minutes

I can spend 30 -45 mins and multiple trips to fill that up and still not hit everything as well as my fogger does in less than 10 mins.
