The MuTech app that you control it with is not great. Initial setup can be confusing and frustrating. The app is also bare bones. The unit itself is robust and so far I'm happy with it. I have a schedule setup on it and have it plugged into a Wemo switch that automatically shuts off when I'm not home so the house doesn't get fragrance while I'm away.
Not strong enough. Just got it 2 weeks ago and can’t smell it anymore
