Review title: Do not use -- safety for your child comes first!
Product review: Although I have nothing against this product, I too went to get my car safety inspected by the California Highway Patrol and was advised not to use any after-marketing accessories. This product has not been crash testing and I did find that the car seat had less "grip" with the seats and more "give". He advised me to use grip lining (typically used for shelves) and I purchased a color to match the interior.
