I'm loving using this portable mist humidifier. This is not my first humidifier, but this is my my first portable humidifier. I'm getting this because this is small and I'm able to setup in my work desk. Also, I'm able to using water bottle to carry the water; this will a lot easy to get the water and super easy to clean after. At first I'm having issue with Polar Sparing water bottle because the cap too small to twist the adapter. So I change the bigger water bottle and it fit perfect. If you want to setup the 2 liters soda bottle it will fit, but it may lost the balance unless you have something to hold the side. Also, other point I'm getting this is the design look great. This will be a best gift for coworker birthday present.
