Vitruvi Stone Diffuser review

The Vitruvi Stone is the ultrasonic diffuser to buy if the unit will sit in plain view. Its cover is matte ceramic and Vitruvi rates it for rooms of up to 500 square feet, which puts it level with Saje's Aroma Om and well ahead of the MUJI and InnoGear units. It has two run modes, 4 hours of continuous mist or 8 hours intermittent, and switches itself off when the timer ends or the 70 ml tank runs dry. The light has four settings, including a candlelight mode and off. Vitruvi lists the price at $129.99, with the white color on sale at $110.49 when we checked, and US shipping is free over $80. The weak points are practical: the box includes a USB-C to USB-A cable but no wall adapter, the tank is small, and returns within 30 days carry a handling fee. A 1-year warranty covers the hardware. Buyers who want a stronger scent without water should look at the Organic Aromas Raindrop instead.
