This is the first diffuser I have bought. It is quite good for its price, beautiful, with a good water capacity. On the device there is an ON/OFF button, Light, and a timer selection. On its remote control there are many extra options for whether you want the steam to come out continuously, intermittently, etc. As another user mentioned, the lid does not snap on, so you need to be a bit careful when moving it if it is full of water. Something I didn't know and hadn't seen in any review until now is that these devices do not heat the water, but the steam is cold!

It even scents larger spaces. I have it in a hallway and its fragrance spreads throughout all the surrounding rooms. Relatively quiet.

I have it in my living room, it is quite beautiful, relatively quiet, and has a large water capacity. It can also automatically turn on and off, I have set it to 1 hour (for anyone who wants, for example, to use it for relaxation before going to sleep). It scents large spaces very well, but I would recommend using no more than 2 drops of essential oil for smaller spaces like a bedroom. Visually, it appears to be plastic up close, but it remains very beautiful, especially when combined with the available colors. The price is very affordable.

Very good, it just doesn't fasten well the top part, be careful not to put too much perfume, it creates steam and it might throw it out

Very nice, smells wonderful and it is like a jewel in my living room....worth its money...buyers should definitely get it...with water and a few drops of oil, it does an amazing job....

Positive:
Beautiful design, beautiful effects to change colors (or to stay in one), quiet (it makes less noise than my laptop, at the moment I am writing).

Negative:
My product often does not turn on when I press the button. Many times I will unplug it and plug it back in, or I will press the button multiple times to "catch" the command. This happens about 4 out of 5 times. That's why it is "good" (3 stars).

Result: It does not scent a large space well, even though I drop many drops. However, it scents a room satisfactorily. I thought maybe the essential oils I bought are not of good quality, but I recently bought essential oils from a very well-known brand and still the scent does not satisfy me 100%.

It fully scents a room or even...an apartment depending on the drops of essential oil that are used. It is quiet, aesthetically pleasing, and comes in a variety of beautiful colors and shades for an even better appearance at night (the mist is visible during the day). It activates and operates immediately. It has a programming feature to automatically shut off after up to 6 hours, it has a remote control, and it is very easy to use. It shuts off on its own when the water runs out. This particular one is double the price of the others, but it holds 500 ml instead of 300 or 400, and most importantly, it has a remote control. I hope it lasts as a device.

UPDATE a little while later: Unfortunately, even though it is cleaned, it produces much less steam than initially. It malfunctions noticeably, just like another device of the same kind that I had purchased

Quiet (you will hardly notice that it's working), for better results you can mix your choice of fragrance in liquid form. Essential oils do not perform as well (compared to mixing liquid fragrance) in this device.
In practice, it is not a humidifier, meaning it will not significantly increase humidity in a closed space. Its actual function is to scent closed spaces, and it does so very well at an excellent price.

Lightweight device. It holds enough water inside, resulting in a long operating time. I add 3 drops of essential oil and it smells incredibly nice throughout the house. It is silent even for the night. It has a timer for 1, 3, and 6 hours of operation, as well as lighting in various shades.
