Review: UPDATE! Don't not buy!!!! - OK so I had to come back on and give another review after a couple months of sitting in my closet I decided to take them out and try again idk how but they actually started working properly and it has been months of constant use without any problems! Just make sure you clean them out regularly I learned this the hard way the top piece that comes off/ where the smoke blows out has developed calcium buildup (best way I can describe it) which has stopped the smoke from blowing out correctly and they don't sell replacement pieces but totally not the companies fault! Great product once u get it working and customer service is GREAT when I had my issues they refunded me with no problem quickly. Literally had this product for 4 days already stopped working. Yes it's nice and big Yes the concept is amazing durability is an absolute zero. Save yourself the headache bad product overall!!!
Review: One gallon of water - This diffuser is a beautiful design, very modern. It seems to shoot out a lot of mist so the humidity is fantastic. The plastic container It is seems to be good quality.. it is a dark walnut, like it said it would be. However, the only drawback is it is not very bright, the color during the day. So if that's what you're getting it for you probably would not want this product. That is not what I bought it for I bought it for the practicality of what it is. And it definitely stands out with that. It has wonderful instructions, very easy to follow. Very detailed and the pictures you can follow along with it. Kudos to them for who made up the instructions. So, remote control seems to work better than touching the machine itself the remote control comes with batteries. It has an exceptionally long cord. For putting it in a living room or something or a bedside table. It does have mist settings option. It does have timer's options. And for the most part, it does have the options for lights. The box was sturdy and it was packaged very well. There doesn't seem to be any flaws in any of the plastic like scratches. And if this is your first time diffuser, it tells you the do's and don'ts in the instructions. All in all, I think this is a very good product. I would suggest someone buying it if you don't like to keep filling.Your diffuser up all the time I would like to add an update here. It does have the capacity of running for 24hrs straight through.. and at night, the light lights up the whole thing.. during the day, you wouldn't have color but at night, it makes a huge nightlight, and it's very pretty. I included a picture for you to see at night. You would also have to add more of your oils about half way down because the smell goes away. Putting in more oil would just make it stronger for a little while.

### ⭐ Top 5 worst products Ive purchased off Amazon! Broke within 24 hours.
*by A***G on November 25, 2025*

Terrible product. I got 24 hours of use out of this unit. Following day I went to refill the tank and the entire gallon of water drained out the bottom vent ports. After removing the tank (view pictures) you can see the bottom of the unit is cracked massively - most likely from the heating element. You can also see in the second picture that the plastic cup area that you use for oil scents was melting. This unit has no longevity and should be pulled from the shelf for insane defectiveness. I will say, it blew out the best plum of steam I have seen yet from a diffuser, and I was in love with the tank size so it can last a full day - but overall this was probably one of the worst items I have purchased off Amazon. Stay clear of this item. Also, the LED light on this unit is garbage. It doesn't diffuse the color throughout the entire tank, just a small LED bulb in the front. Way more negatives than positives. Steer clear! I should have listened to the 1-2 star reviews.
