  • Beautiful, Quiet, and Works Wonderfully!
Color: Dark
Everlasting Comfort diffuser is very nice looking. I bought the dark grain wood and I couldn’t be happier with it. The diffuser it’s is beautiful. Yes, it looks sort of like an onion, but it’s very elegant looking. I have mine in my bedroom on my desk. I ordered the plant therapy oils to use with it. The diffuser is easy to use and hold 400ml of water. It’s very simple to fill up. You pull the top off vertically and there is a deep and fairly large reservoir. Fill it to the 400ml line and add a few drops of oil and slide the lid back on. Simple! There is two buttons on the back. The first is for the light, which features several different colors to choose from. The light is vibrant and add even more beauty to the diffuser. Next to the light button is the on/off switch. There are three settings, 1 hour, 3 hour, and 6 hour. I use 3 hour often. The scent fills the air too. I especially love how quiet this unit is. I literally forget the diffuser is on all the time. Don’t worry, the diffuser shuts off after it runs the cycle you choose. I recommend everyone who is looking to a pretty and quiet diffuser to buy this one. Plus, it comes with a 1 year warranty. ... show more

  • Of my dozen diffusers, this one diffuses the most vapor
Color: Light
I have or have tried at least a dozen diffusers over the last five or six years. I'm heavily into young living brand oils. Of even their diffusers, this diffuser emits the most vapor, has the biggest reservoir, and is good-looking. (I have the lighter one.) It has all the necessary functions like a timer and lighting. If you want one with a lot of light, this isn't it. It has a slim strip that changes color. I don't care for that function anyway. I'm looking for scent. With a 400 ml reservoir, you'll need to replenish the oils after a couple of hours to keep the scent fresh. The vapor is rather thick. It's practically a humidifier. It shoots straight up and doesn't leave anything wet. To keep my diffusers working for years, after about five hours of use, I rinse them with Dr. Bonners liquid Almond-scented soap (use any scent) or a drop of Dawn dishwashing liquid and a soft bristled toothbrush. This one comes with its own cleaning brush. Be careful around the disc. I've been using mine for about two months and love it so I'm back on Amazon buying another one. It scents our extra large master bedroom with vaulted ceilings. I've had much more expensive ones that don't do nearly as good a job as this one. It's tall rather than wide so it sits nicely on my night stand. I think you'll like it! ... show more

  • Loveliest Essential Oil Diffuser I Found
Color: Light
I searched the internet for a long time before I bought this diffuser. It is beautiful and works like a champ! It comes with a cleaning cloth and brush, so you can care for it after each 5-6 uses. As it diffuses, you can see different colors which creates a zen like feeling. For some reason, my engineer husband finds the color changing fascinating. Because the colors come from a small strip, it is interesting without being overwhelming. The instructions are clear and easy to understand. Add water to the line, add 3 drops of essential oils, push one hour or three and enjoy the lovely aromas. I used it first when we had steamed shrimp. Love it, but UGH the smell lingers for days. The diffuser substituted a pleasant aroma! I recommend this highly and will probably buy some for gifts. It comes with a lifetime replacement guarantee and a 10% coupon for your next purchase from their web store. ... show more

  • Long lasting mist
Color: Light
I've had a few other essential oil diffusers. This one is the largest I've purchased. The amount of water it holds creates a long lasting mist that goes the whole night and well into the next day. I have to use at least twice as many drops of oil in this diffuser to get the same level of scent I did with my 300ml diffusers. I use 10 to 15 drops, but even then, the mist seems to outlast the scent. Overall, it is quiet, nice to look at and seems to be working properly. I am satisfied. ... show more

  • My favorite diffuser for large rooms, and customer service is wonderful.
Color: Light
I have a few diffusers in my house, and this one ended up in my bedroom because it gives off more mist than any of the others for a longer time. My previous diffuser for my bedroom didn't seem to put any scents into the air even when I increased the essential oil I put into it. With this diffuser, I set it to ON and then hold the mist button until I hear 1 beep that signals the high mist mode is on. High mist mode can be chosen for each of the timer settings. Now I can smell the wonderful scents, and the mist still lasts all night. Since this diffuser holds 400 ml. of water vs. the 150-200 ml. that many hold, it can be set to run continuously for up to 13 hours. The timer option allows you to set it to run for 1, 3, or 6 hours or continuously until it runs out of water at which time it will automatically shut off. The option of choosing 1 of 7 lighting colors or a rainbow of all colors is also a nice touch. After about a week, my diffuser stopped working - neither the mist or the lights worked. I decided to try the power cord from another diffuser and it worked. The power cord from this diffuser did not work in the other diffuser. This indicated that there was a short in the power cord for this unit. I sent a message to the seller describing the problem and asked if I could get a replacement power cord. The next day, I got a message from them saying they were sorry about the problem and were sending me a replacement diffuser. How refreshing that a seller stands behind their products!! As mentioned previously, I have multiple diffusers in my home, and the oils used in them depends on the needs at the time. In my 98-year-old mother's room, I often use a Breathe Easy blend when she has a cough or congestion in her chest. There are also blends for stress relief, sleeping, and so many more. I use the diffuser in my bedroom every night as the scents are relaxing and I sleep better. If my mother or I have a problem with congestion, the oils for this purpose relieve the congestion and make breathing easier. For my bathroom, I enjoy the sweeter more flowery scents like lavender. These scents seem to help me to get my day started feeling more positive. Whether or not you have tried aromatherapy, this diffuser is definitely a good one to have, especially if you want a stronger scent that will last throughout the night. It's also good to know that the seller stands behind the quality of this diffuser. UPDATE 11/25/18: I have been using this diffuser in my bedroom for about 6 weeks, and I still love it. Even on the high mist mode, it lasts the entire night and shuts itself off when it runs out of water. I do like the hi mist mode as my bedroom is relatively large, and this mode fills the room for the entire night. I have been happy enough with this diffuser that I have bought another one for a different room. UPDATE 10/07/19: I have been using this diffuser every night for over a year, and it's still working as well as it did the day I bought it. I also bought one for my mother's room shortly after I bought this one, and it is still working as well. She is 99 years old and sometimes has a runny nose. Using this diffuser in her room at night seems to help her sleep better, and reduces the her runny nose. I use one in my bedroom because the fragrances are relaxing after a hectic day. 08/11/2020: I have been using this diffuser in my bedroom and in my Mom's for about 2 years. Since so many products sold today don't last for even a year, I am very impressed with this diffuser. Both that I have are working as well as they did when I got them, and, honestly, I haven't cleaned them as often as I should. I am sold on the benefits of essential oils as they have helped my mother a lot with breathing and congestion. They have also helped me to relax at night when I go to sleep. If these diffusers should ever stop working, I can assure you I would buy them again. I should also mention that this review was not prompted or paid for in any way, and is entirely my opinion based on my use of this diffuser. I hope the review was helpful for you in choosing a diffuser that will work for you. ... show more
