First off...I'm going to state this up front. The rating I'm providing is based on the quality of the product, NOT the price. This item is not worth $150 (at time of writing) with so many other similar options out there available for less. However, if this went on a nice sale at some point, it could be worth picking up! Now, on to the review.This unit is exceptionally well made, and feels very premium. The entire exterior is metal, and the top is knurled to allow for an easy screw-off, as well as looking fantastic. I got the silver model, and really like it. It comes with a built in battery, which I really love, as it allows you to really put it wherever you need to. Our kitchen has an area that frequently gets "musty" smells, so I've put this in that area and completely eliminated our ability to smell the mustiness.I also love that this uses straight essential oil; no having to worry about mixing oil and water with a carrier oil in specific quantities, etc! That also means that this is VERY POTENT. You do not want to place this unit super close to where you'll be standing/sitting, as the mist will go up your nose in a not very pleasant way. The best way to use this would be to put it in a corner of the room and let it waft around and disperse through the air.Like some others have mentioned, one small disappointment is that it doesn't have a fan to blow the scent around, so it won't cover as large an area as advertised without help. If you are able to place this in a room with some airflow (such as a room with HVAC or something) it should cover quite a large area, especially on a higher setting.Some people weren't a huge fan of the plastic bottle that's included...I honestly don't mind. Glass would have felt a bit more premium, but it would also add to the weight and is easier to break. That's more of a personal preference.Like others, I did not get a USB-C cord included with mine, however I have about sixteen thousand five hundred and seven of those sitting around the house, so I did not care as I would have thrown it away anyway. They just shouldn't report that they include it if they plan not to. The bluetooth function works well, and I didn't really have much of an issue setting that up. You definitely don't have to unless you want to control it remotely or set schedules; if you're going to leave it on 24/7 you can just use the button.I have almost nothing negative to say about the unit other than the outrageous price point. If that price comes down significantly during a sale...this is a stylish and exceptional unit!
