250ml Aroma Essential Oil Diffuser, Portable Ultrasonic Aroma Cool Mist Humidifier with 7 Color Changing LED Lights, Waterless Auto Shut-off Function (250ML)

This is my first oil diffuser so I am a newbie, a seasoned diffusing veteran may be more picky than I am. I wanted something to use during the work day (not just an hour or two) in my office because sometimes it smells a little musty from the HVAC system. My office is very quiet and this unit is quiet as well, just a faint fan sound and then the gentle sound of water. Not distracting at all, more of a very low level white noise. The beep when selecting the timer or light is not loud either, don't know what other reviewers were complaining about there. I love the fact that this can provide a scent all day. Not to sound like a total 5 year old but the slow and continuous changing colors are a fun way to break up the monotony of work. You could also select each color individually to remain on in a bright or lower setting or to just stay off all together which gives a lot of options. The strength of the scent probably depends a lot on the quality of your oils, I haven't had any issues with the scent in mine fading although it's pretty obvious you are going to get used to a scent if you sit in front of it smelling it all day. My office is about 11 x 18 feet and it fills the room easily. You can faintly smell it about 10 feet from my door as well. You can definitely see the vapor as it comes out the top. Love the auto shut off feature. So far, it's a great product and one of the lowest priced at the 300 ml capacity.

I've used this diffuser several times and it just doesn't work well. It runs, emits a faint scent, only uses half of the water/oils I place in to it on any given day-does not shut off, just keeps running. There are times, frequently, that I diffuse different oils on different days. I am not sure if it clogs or what. I feel I ultimately waste my precious ($) oils and then, get discouraged and don't use the diffuser at all for fear of waste.

Honestly I wasn't expecting much since it was so cheap. But it seems like a nice solid little machine. The vapor output is AMAZING. Yes, the buttons are loud-ish when you press them, but I think it's a fair trade off for a 300ml diffuser under $20. We put it in our Guesthouse and it is working splendidly. Thank you!

I've never write a review about my Amazon purchase but I just couldn't pass through this horrible product.1. Broken:The inner cover came off from the top lid when I opened the box. The mist port wasn't on the right position so I couldn't use it. I tried to fix it with my glue gun but I asked myself " why do I have to do this"2. Noisy Botton:The light bottom has make a beep sound every time when you push the Botton. It's Too Noisy, so annoying!! If your partner or kids slept already maybe you need to give up to choose your favorite color.3. Changable color????:When I turn on the mist, the changeable color was suddenly turned to a fixed red color!! You can't use the changeable color with mist. What a funny!!4. TOO LOUD!!!!!!!!!!!The mist, OMG, it's AMAZING LOUD!!!! NO WAY to use it in the night time!!

Out of 5, 2 stopped working less than 90 days after purchase. 30 day return is all that you get for these. I was told to contact the manufacture and that there is a listing of numbers for "some" of the manufacturers. SOME??? If this is the practice of Amazon,not to stand behind what they sell, I'll be looking for another on-line store. Very disappointed in the product as well as my overall experience with Amazon.

Pretty lights. Does the job.

I kinda LOVE this beast. I got a smaller one as a gift and I keep it by my bedside. This one I keep in my kitchen where my dog lives most of the time. You can work this one to nicely tone the smell of your whole house depending on oil distribution. I have 2500sq feet and you can smell it lightly throughout, including downstairs. I love it and the options!

Meh, it's OK. Cheap but simple design. Smaller volume than I expected - 300ml is only about a cup. IMHO, you'd probably be better off spending a few more bucks and getting one from a reputable brand. The single button design is simple, but you need to press it 15 times to cycle through to the option you want. But otherwise, it works fine and we use it often.
