This is the top-of-the-line Jiaiino FMV5400. It has been unboxed, and the water and tablet insertion have been confirmed to be working. The tablet is full. It can be used immediately upon arrival. This is the highest-end model with a humidifying function. I have hardly turned it on since I got it. The filter is almost new.
