Jumbo size
I have several diffusers but this is the largest by far. I will hold a half gallon of water. There's two buttons on it similar to other diffusers with a low, medium, and fast output. Its has small rubber pads on the bottom to keep it from sliding. So far no problems and on the low output it runs all day without needing water. It runs very quiet. I received it at a discounted rate for my review but it's worth the full price for the size. I would definitely recommend.  Just as described.
