I had the older version of this Humidifier and definitely love the new features. I love how you can fill the tank from the top and unplug the cord from the humidifier. The sound machine doesn't have a ton of options, so we will use one we had over this one. It is easier to clean as well. We do have hard water so I will be interested to see how it holds up over time, since with our old one we had a filter and that doesn't seem to be an option with this one.
