Works exactly as described and looks beautiful. The tank is a good size, it relaxes me and even helps with my sinus trouble, which is the reason I bought it.

Hiro's Hearth — a fireplace-shaped aroma diffuser and air humidifier. The flame you see is cool ultrasonic mist lit by LEDs over glowing simulated logs: nothing burns, nothing heats up, and you can pass a hand straight through it. 150ml tank runs 5+ hours; three timers (1/3/5h) and auto-off dry protection; seven flame colours plus a separately lit panel, all from the included remote. Whisper-quiet at about 30dB, USB powered.

What buyers say.
Left by buyers of this model on the manufacturer's listing, not by Hiro's customers yet. We swap them for our own as soon as we have enough.
The flame flickers so convincingly that first-time guests hold a hand over it to check. Drops of aromatherapy oil and the whole room softens.
You can set the panel light and the flame to different colors, which looks fantastic at night. The remote does everything from the couch.
The 5-hour timer lines up almost exactly with a full tank, so I just refill in the morning. Quiet enough to forget it's on.
