Works perfect as advertised the whole house smells amazing. I would definitely recommend this product.

I absolutely love this machine. It’s consistent and the scent is light and not overpowering. Excellent investment.

Thanks for the nice product, and great value , it's working very well, without any problem, easy to program. Thank you very much, for your service. Wish you the best.

Excellent product and well worth the money! Works well in room or through ducts. I like being able to control the scent.

The unit works very well. Easy setup. The bottle locking mechanism was weird for the first time. I use it on the lowest setting in a 24'x30' room (5 sec on 300 sec off) . According to the app it will last almost a year without refill.

Excellent high outlet diffuser. With covers my entire first floor, 1600 s.f. with aroma. I like that u can control the intensity of the aroma and frequency of usage.i had two other manufacturer's cold air diffuser, they didn't have the aroma output like this one. The secret is buying good high quality essential oil. Highly recommended.

Purchased this small one to sit in a small room. Works great and is Bluetooth controlled. Put out just enough fragrance that can be controlled by your phone.

Absolutely love this scent machine. I had paid over 300.00 for the first one I bought. And this one is better than the expensive one. It's easy to program. Absolutely love it. Gonna order another soon

This cold air scent diffuser is super easy to set up and use. The app is no nonsense and easy to follow. The machine does look very industrial, but when I was shopping around for a diffuser, I was seeing over $100-$200 for a machine, and this sturdy machine was much less.

The only complaint I have about this wonderful experience is, it really does irk me. I say this with all due respect, why don't you carry extra bottles?! THANK YOU FOR MY BEAUTIFUL SMELLING, HOME !!!.................
