I really like this model because it provides a wide angle of view. In addition, you don't have to squint to see moving cars in the background. I have a Toyota Avalon, and the mirrors are almost too big. The sticky tape on the back really does hold. I was not able to put it on straight and tried to move it to be straight and the sticky tape had already taken. I was not able to move it.
I like the fact that this is bigger than must Blind Spot Mirrors it gives you more area to see.
I don't mind the shape I just in fit better into the corner of the rear view mirror.
