Smart Scent Air Machine for Home, Waterless Essential Oil Diffuser 100ML with Nebulizing Diffusion System,Portable Scent Diffuser with USB & Battery Powered,for Large Room,Home,Office, Spa,Bath Room

Purchased my diffuser and waited a week to review it. The reason I love this diffuser is that I can place it in remote places where electricity is not available due to its very effective and useful 2xD battery compartment. It is both Usb C and D battery operated, you get to choose between the two by flicking the on board toggle switch. As far as how quiet it is Wow! If you're an asmr white noise type of person you'll be pleasantly surprised at the soothing sound when it turns on. Oh yeah and the amount of punch the small footprint of Diffuser packs is amazing! Very easily fills a 500 ft room. Will definitely be buying a second one for my office. Also was pleasantly surprised at manufacturer extending warranty to two years just for registering the device! If you're on the fence please don't think about it. Money very well spent.

So my wife told me about this machine and I totally did not believe that such a machine could exist and if it did it could not be cheap, would consume tons of power, would be a hassle, could not possibly provide a scent for that long without the hassle of constantly replacing the scents (i just picture those dumb car tree scent car wash things that last for maybe 1 day). Well, boy was I proved wrong. This little machine is WAY underpriced for what it can do. At this rate we have it plugged in and have all kinds of spray schedules to my wife's delight. The oil lasts FOREVER, it has either battery or USB power. The bluetooth app takes a bit of learning to get used to, but once you do, it's not that bad to set up the 5 schedules. We loved it so much we bought another and plan to buy yet a third. I still don't understand how all the other manufacturers haven't jumped on board with all the capabilities this thing can do and for such a small price. Highly recommend but if you are not tech savy, you may need to find a tech savy kid to help you set up the bluetooth schedule, else the default setting will do the trick but be spraying quite a bit, so your oil mileage may vary.

Stopped working within a month!

Easy to use and works well at the lowest setting. Doesn’t overpower a room. Has up to 5 time setting you can choose so set it to come on just before you wake up, turn off at night, turn on/off mornings you go to work and back on just before you wake up…

I purchased this to scent a 18' x 12' room with a vaulted ceiling. I've used diluted and undiluted essential oil in it--primarily eucalyptus. I plug it into the wall, rather than use batteries. App works well. HOWEVER, it does not even begin to scent the room. Almost no scent at all unless you are standing right next to it. When you call the vendor, HOMAS, they tell you they only support commercial applications and refuse to talk to you. If you have a small room, this might work, but, otherwise, don't bother.
