Pros and cons

Pros

Large 8-liter tank with top filling may make routine refills less cumbersome.
App and remote control support adjustments from a distance, and auto mode offers a stated humidity target range.
Four mist levels, a timer, a rotating nozzle, and a light that can be switched off provide several adjustable-use options.

Cons

The product is listed as ultrasonic, and the listing notes that water with impurities such as tap water can produce white dust. It recommends distilled or filtered water.
Essential oils must go in the aroma pad tray, not the water tank. The listing warns that oils elsewhere may crack the materials.
