Bests & Worsts Reviews from Amazon

I bought this humidifier for our smaller, guest bedroom and on the first day I used it, it stopped working after a few minutes. There is a problem with the flow from the tank to the ultrasonic actuator and as the level of the water goes down, over the actuator, no water flows from the tank to replenish it, the red LED turns no signifying that there is no water and the unit turns off. If you move it, causing water to flow down, the indicator LED turns green and the unit turns back on. Obviously, this is not something you can do every 30 minutes, especially at night when you try to get a good night sleep... I messages the seller about it, hoping for an RMA and refund but got even better. The seller instead promised me full refund and does not even want the (useless) humidifier back. I wish this humidifier was as good as the seller. It would be the best humidifier in the market but considering its performance, I cannot recommend it. It gets one star for the seller though!
