Review (4/5): InnoGear Oil Diffuser -Works like it should
I had a smaller diffuser like this one. The top become very frustrating to remove so I purchased this one , which holds a little more water. What I have a problem with is opening and closing this design diffuser. My hands tend to be dry and the plastic top is very slick. I decided to add a wrap of colored electrical tape to help me be able to grip the top. Other than that, it works like it should.
