The device once setup works great. The app and instructions are horrible and deserve low stars but if you can connect to Alexa the device works great and produces a great amount with little to no noise. Would work great stand alone with out smart features if needed. But the smart features set this device above the rest. It just takes som effort to get it properly connected.i
It is very ascetically appeasing and brings great smells into my home. It works well with the google assistant and works great with my set up. However I did take out a star because although instructions are given, it can be a little tricky/or confusing to set up to use with a voice assistant. If you don't know much 2.4 ghz or what channel your router is on, then you may run into problems. Even if you know its still a process and the functionality is basic, turning on and off, but the app itself provides more control.
