SWEETFULL Waterless Essential Oil Diffuser – USB Aromatherapy Diffuser with 30/60/120 Min Adjustable Timer and 16 Mist Modes, Scent Diffuser for Home Room Office Hotel

Step up!
I love not having to deal with water!! Only negatives- wish I could set it for longer than 2 hours; wish I could see to set times without it running in my face; wish it world remember the previous settings so I didn’t have to reset every time.

A little noisy, but it works really well
This essential oil diffuser works really well. I like the fact that it does not require water, and the fact that I can control how often and long it disperses. I think the unit is a little on the noisy side, but I don’t run it for long or too frequently because of my small dogs. I wish the instructions were a little more thorough. I actually had to read some of the reviews to figure out what the actual settings for time meant. Basically the TIMER determines how long the unit is on. There is just an “on” setting so you can have it on all the time, if that is your preference (I tend to set mine for 60 minutes and power it on a couple of times a day, so the unit will run for one hour from the time I turn on the power button). The “ON INT” determines how long the fragrance will spray into the air, and you can choose short bursts or up to a solid minute. The “OFF INT” determines the amount of time between the spritzes, with the same timing options as the ON dial. So, as an example, I have the ON button set to 5-seconds; the TIMER button set to 60 minutes; and the OFF button set to 60-seconds. Once I push the power button, the unit will spray for 5 seconds every minute for an hour, and then it shuts itself off. This is a good setting for my purposes, as I want my house to smell nice without I or my dogs feeling overwhelmed by the scent. This also ensures that I never run the unit till it’s dry, as it does not have a feature for shutting itself off if it runs out of the essential oil. Fortunately, the glass jar does allow you to see how much is left, so you just need to get into the habit of looking at it. Since I use the timer feature, I check each time I power the unit up.The unit is small, which I appreciate as I don’t have a lot of room in my house, and it looks nice. It works smoothly and easily and keeps my home smelling fresh. I wish it were a little quieter, but I am overall very happy with this diffuser.

Weak features, no power adapter
First off, the box this came in said it runs on 100-240VAC, and the user booklet refers to a power adapter. But none was included, so I had to supply my own USB wall charger to even turn it on. Loading the oil was a challenge, the instructions are very sparse, mostly drawings, and don’t really explain how to get the glass bottle off. In fact it screws off, but you can’t get a grip without removing the entire assembly by pulling down on it. Finally, the usage settings. It’s a very small oil bottle so it seems you would want to stretch out the misting. But the timer only goes out to 2 hours–unless you select continuous. The most infrequent timing interval is 5 seconds every 5 minutes. The product does work, not the quietest machine but it does the job. Still, I feel the design wasn’t well thought out….

Pure scent – not watered down
This is a very nice and small scent diffuser. It doesn’t come with scent – just an empty bottle that you fill with the scent of your choice. It comes with a USB cable that you must use to power the unit. That’s my only complaint – it’s not cordless. But I can get over that because it is so adjustable. You can choose how long it sprays, the time between sprays and how long you want it to work (30/60/120 minutes) before shutting itself off. That simple. I do wish that it would remember your settings between uses, but I’ve set it it 3 or 4 times and already remember my settings by touch so no big deal. It’s also one touch on and off. There is an “s” after the first four settings on the spray timer and interval timer which I have no clue why it’s there. It just puts you back to the beginning when you land on it.I think it puts out a good amount of scent with each spray even set at the lowest spray setting of 5 seconds. If it’s not enough, I can just adjust it to 10, 30 or 60 seconds. I’ve used 2 very different scents – one I added to the bottle that’s included with the diffuser and another bottle similar in size that fits. I’ve wiped the spray area and nozzle that goes down in the bottle when changing scents and haven’t noticed any mixing of scent after the change over. Very simple to use. I do like this product and will get a lot of use out of it.
