I really like this humidifier. The removable lid makes it real easy to add water. You can also pull out the water storage bucket and take it to a faucet if you want. The design of the float, ultrasonic element and heater on the bottom makes it easy to clean, just pull out the bucket and you have open access. The night mode is really great. I've been using only distilled water in mine and its real easy to keep clean with almost no deposits. If you put it on medium or high setting, it will really go through the water if you need a lot of humidification. I have been using it now for almost 6 months and its been great.
