I love this machine. It is stable, has a big water reservoir and is very quiet. I got a machine from my insurance. It fell off my nightstand and water got into the machine. It won't turn on any more and my insurance won't give me another one. I wanted something stable and heavier so it won't fall off as easily. I don't travel much at my age so I don't mind it bigger. My mouth gets dry so I like that I can put a lot of water in the reservoir. The water lasts all night and still have water left. This machine works great for me.
