The device generally matches the description. The "flame" effect is fairly subtle, but it looks particularly nice in the evening when the lights are dimmed.
I mainly use it as a diffuser with a few drops of essential oil, and it does the job well. It’s easy to use and simply plugs into a USB port.
The water tank is on the small side, so you have to refill it regularly, but it’s sufficient for smaller rooms or occasional use.
All in all, it’s a solid product that creates a pleasant atmosphere without taking up much space.
