MythGeek 500ml Aroma Essential Oil Diffuser Ultrasonic Air Humidifier with 4 Timer Settings 7 LED Color Changing Lamps

I have had this, my 2nd, diffuser for 3 weeks. I run it constantly on high when I'm home and get a good 10 hours from a full (500 mL) reservoir. I usually don't use the light, but it cycles through about 7 colors (white, pink/red, orange, yellow, green, blue, purple) in 2 min 45 sec, and is very pretty and soothing. It's whisper-quiet (you can only hear the fan if you get very close to the unit). The ultrasonic mechanism causes the water to agitate and lightly slap the cover (be careful not to turn it on while the cover's off or the water will splash everywhere), which creates a slight bubbling/gurgling, but it's not loud or distracting. When first turned on, it's difficult to tell whether it's on low or high, but after a while you can definitely tell because on high the mist pours out of the opening. I have used 13 different essential oils (including citrus) in it with no problems with any, except that the colored ones (e.g., grapefruit, tangerine) leave a little residue on the lid, which is easily wiped off. I also have a 100 mL diffuser, which is great, too, but for a few dollars more you can get this one with 5x the capacity. I will note that, at least on mine, and unlike the smaller one I have, the lid does not lock into place. This is actually a good thing IMO because the diameter of the lid is 6.5" and it would be difficult to grip and twist to unlock rather than simply lifting off. I would buy this unit again.

i just recieved my diffuser. last night i read and followed all directions to a tee. when i filled just under 500 ml and added two drops of oil...not three...it was working great. this morning when i got up the unit had shut off at 400 ml mark....so it only burned 100ml. the lights worked although i thought they changed from one light to another but that is not my real concern. my concern is that the unit shut off after using only 100 ml of water. so i emptied the unit and shook for excess water as the directions stated. I will wait until tomorrow night giving a good 24 hours and will try to use the unit once more. if it doesn' t work tomorrow night again then i will be contacting Amazon to invoke the 1 year warranty stated in product description and I will then expect a replacement. I am disabled and had a severe fire in my apartment. i am gradually replacing things. with that said.....i don't have a printer just yet to print labels so I WILL NEED HELP WITH THE RETURN SHIPPING.thank you.

Our 2 year old has severe eczema and just recently started having some trouble sleeping. After some suggestions from friends we started a little research into essential oils and decided to give them a try. There are TONS of diffusers out there, but a big concern for us was the size of the tank as our house tends to be very dry. This does not disappoint. It works wonderfully and you can tell it's working almost instantly. This is much quieter than his old humidifier, much smaller, and the oils are an absolute god send. The first night with this was a total game changer!WARNING FOR PARENTS WITH BABIES WHO SLEEP IN DARK ROOMS: 2 things -- 1) Our guy is used to a very dark room, but we thought the different colors would be a great back up plan in the event he needed a night light down the road. This is VERY bright. I would suggest it more for a bigger room or a play room, but not a nursery or small bedroom. It's waaay to bright for a night light. 2) The power light on this is also very bright. I'm sure it's fine if you have light spilling into your room already, but for a child who is in a completely dark room, this LED is over powering. I simply put a piece of painters tape (FROG Tape to be exact) over the light so we could still see the light, but it wouldn't be so overwhelming.Some people complained that they couldn't tell when it was on high or low, I figured this out pretty quickly. When you turn it on its automatically on low. If you press the button once it beeps once and keeps it on low. If you press it a second time it will beep twice and you will see a dramatic difference in the output of vapor. Not hard, just turn it on and press the "mist" button twice.

In my opinion this is the best Essential Oil Diffuser on Amazon. When I first bought diffusers I purchased 3 different kinds, I would have kept them all if they had met my needs, but only this Noza Tec 500 ML met my needs. First, it has a huge tank which literally lasts for 20 hours. Second, I've been using this daily and it still works perfectly -I say this because I purchased another 500 ML difffuser made by another company and it broke before a week was up. Third, the colors are pretty -I didn't think that I would like the colors but I do. Fourth, I have recommended this diffuser to 5 different people and they have all purchased, and they are all as happy as I am. This diffuser is not a piece of art, but instead a hard working machine. There are some diffusers out there that are beautiful, but their prices are not beautiful; I am a teacher and use this in my classroom, my students love it and they take turns picking the color for the day, if I don't have the diffuser running by the time my students get to school they are fast to remind me to turn it on. If you are like me and you need a good solid diffuser that will run for 20 hours then shut itself off, then buy this one, it is the best priced and best working diffuser on Amazon. And, no, the company didn't pay me for this review - I love it when a product works the way it is supposed to and I want to share my research and information with you, the Amazon shopper. I read reviews and my purchases are swayed by the reviews. Let this one sway you into buying the best diffuser. at the very best price
