If you're putting in a drop ceiling and need ceiling tile diffusers for your heat and air look no further. These diffusers work great, are easy to assemble, and they look incredible. The plastic construction is a plus, it gives them a clean crisp professional look, as opposed to a lot of the metal ones I saw that have an almost we'll call it retro stamped look. The best way to describe them is they fit seamlessly into the ceiling where they actually go unnoticed. I have to draw attention to them when I'm showing off my new ceiling. One of the ceiling diffusers I purchased was getting placed in an area with a custom color ceiling, so I lightly sanded the parts, painted them, and then assembled, again looks great. I definitely recommend these.
