I love this thing and im glad I went with the product reviews, I used it because I have a truck with a baby seat in the middle. There is no headrest there and not being able to see my boy sucked. I tried propping up the headrest mirrors up between the window and seat and that didn't work because my window would move it everytime I opened it. So I found this and the best part about it is that it is infinitely adjustable, its optically clear and big enough to where I can see and communicate with my son and still be able to see out my back window. Love it.
