I love this vaporizer for multiple reasons. It holds a lot of water, which makes it able to last a long time, in my experience it lasted a lot longer than the manual said it could. It has a steam guard, to protect you or anyone else, like a child from burning themselves. It has a nightlight so you don't kick it when getting in or out of bed. The vaporizer works very well, it says it's meant to run for something like 12-14 hours, but i had mine on for over 24 hours and it still had tons of water in it and was running fine. It's lightweight and easy to understand how to use it. You can use either Vicks vapor liquid or Kaz brand liquid inhalant. Both me and my sister used it when we got sick and it definitely fille up her whole room with steam and the inhalent, i believe it helped her a lot. For me i don't believe i had enough inhalant in it after she had used it, but nonetheless it still worked well and was not overpowering.
