Love this product!!! I received it 3 days ago but did not unpack it for 2 days.Pros:1. Great build quality. The device feels solid no cheap plastic or resin material. Feel like solid metal/steel.2. The unboxing experience was great. Well packaged to keep it from being damaged. Company provided included a handwritten note.3. Modern slim design and fits into most home decor and design4. Fantastic customer service. When I first unpackaged the device and, selected my oil to use and then plugged it in, nothing happened so I immediately thought the product was defective. I tried it for 10 mins and nothing.So I decided to email the Company via their help desk. I was contacted the next day by Jeff. Jeff was super helpful and very responsive to my email and follow-up questions and even offered to call me to walk through troubleshooting. Jeff provided some 3 tips via email to take a look at and low and behold checking the device helped. I think it was the straw insert that was not properly inserted and connected. I emailed Jeff back to let him know that I was able to get the device to work.5. It comes with a remote to change settings (although I wish it had bluetooth).6. Last but not least, great price. For the quality the price of less than $180 (US dollars) is fantastic!!! There's another similar one on Amazon that is over $300 dollars but this one seems just as good and has a better price point.7. Also one more thing, love the fact this diffuser does NOT need water....as with traditional ultasonic diffusers.Cons:Of course, as with most things in life, there are a couple of cons or suggestions that I have.1. I wish the device had bluetooth technology. Now I know there is a trade-off sometimes, features vs price, so I suspect that if the device had BT, the device would be well over $200.2. I wish the device came with a second oil canister, this way you should switch out oil fragrances more quickly
