I bought this rather than using plugins. I love the tool so far. It was easy to set up using the instructions. Only issue is the app.; I have it connected but it crashes when I attempt to access the schedule. It would be nice to have but I programmed my unit at the unit so no problem there.

Absolutely perfect for residential use.

I've had this machine for several years. Although they state the scent in this size (27 oz) can last up to 52 weeks depending on settings and the space, I have found this not to be true. $200 (on their website) for 27 oz for (what I was assuming to be) a years time was totally reasonable....Unfortunately, it was running me about $200 per quarter for my 4,000 store in order to be noticeable.
