When readers message me, “What diffuser should I start with if I don’t even know whether I’ll keep up the habit?” this is the one I'd recommend. URPOWER’s second-gen 300 ml unit looks plain, but I’ve clocked hundreds of hours on mine and the thing still works perfectly. The four timer buttons (1 h, 3 h, 6 h, and continuous) sit right on the face. Runtime is 6–7 hours on normal output, creeping toward ten if you drop to the weaker mist, which is plenty for an evening wind-down or overnight humidifying. The 7-color LED ring is fun but not blinding; I leave it on low teal as a bedside night-light. I still think it is a gimmick, but it is occasionally useful if you don't already have a bed light. Clean-up is equally no-drama: a quick rinse plus a cotton-swab swipe around the ultrasonic plate once a week works well with my home oils.
Because the reservoir is polypropylene, I’m comfortable experimenting with heavier blends. I even went as far as a 30-drop eucalyptus bomb and need not worry about plastic degradation. Although, I would definitely not recommend going that far (way too strong!). Pop the lid, measure directly with a kitchen scale if you’re that precise, and you can dial in repeatable recipes. It also has a nice auto-shut-off which means the diffuser dies gracefully when you forget to top it up, which I do more than I’d like to admit.
Some users reports that it works best at half capacity, but I have yet to see evidence of it from my use. It seems to work the same at all capacities. Just make sure your blend, home-made or not, is well-mixed and potent enough depending on how much water you add.
Cons:
LED ring can’t be dimmed all the way to “off” without killing the mist—annoying for pitch-black sleepers.
The lid’s silicone gasket stretches after a year or so; mist output dips until you replace it (a US$3 part, but extra hassle).
Matte plastic stains if you leave citrus oils sitting overnight; a vinegar soak fixes it, but still. (NOTE: this doesn't really affect the smell from my experience, you don't have to clean it)
