This Review Title is Great Diffuser, but Won't Hold a Shape and the content is: This, so far, is my favorite diffuser. The only issue is that if you want it to hold some sort of shape or size, the diffuser collapses with even a bit of pressure. That's not the worst thing in the world, and it's easier to store because it is collapsible..There are other information for this review, one is This reviewer did purchase it and the other is 2 people think this review is helpful.
