The one way to make it leak is to overfill it. Past the max line the water has nowhere to sit and the ultrasonic disc cannot vibrate properly, so you get seepage and weak mist at once. Fill to the line, carry it to the table rather than filling it in place, and it stays dry. Anything that leaks out of the box is a replacement, not a debate.

In bright daylight, yes — you will mostly see mist, and we are not going to pretend otherwise. This is a night object, engineered for low light, the same way nobody lights a candle at noon and calls it disappointing. Draw the curtains or wait for evening and the illusion is hard to argue with.

Bedroom, office, bathroom, reading corner — comfortably, on three to five drops. An open-plan living-dining space is asking too much of a 200 ml tank, and any brand claiming otherwise is setting you up to be annoyed. Ambience first, scent second. That order is deliberate.

That is what it is for. Under 25 dB, no fan, and a smart chip that cuts power the second the tank empties — so the worst case at 4am is that it is simply off. On low output it will still be going when you wake up.

The killer in this category is limescale, not build quality. Empty it when it sits unused, wipe the tank every few days, and once a month clean the disc with a fifty-fifty water and white vinegar mix on a cotton bud. Use distilled water if your area is hard. Covered for a year regardless.

Dispatched within 24 hours on business days, tracking sent the moment it leaves. Live with it for 30 nights and send it back for a full refund if your evenings do not feel different. It runs off USB with no internal battery, so use a 5V/2A adapter rather than an old low-output phone plug — underpowering it is the most common cause of weak mist.
