We purchased this product as we are new grand-parents who once again have a rear-facing car seat in the back seat. I must say that the construction quality of this product is superior to what I expected...it's ultra-wide field of vision is great for both the front seat passenger and the driver...the installation is a breeze as well! The only reason I did not give this five starts across the board is related to the fact that once set, you can't "lock" the mirror position into place. What with getting a baby into and out of their carseat, my shoulder has a tendency to "bump" the mirror and move it slightly. It would have been nice to have a locking screw to ensure that the mirror does not move once fully installed. Don't get me wrong, we're VERY happy with this product and would recommend it to anyone.
