With the Safety 1st Rearview mirror, you always keep an eye on your children in the back seat. Does your little toddler sleep? Which of the 2 toddlers has started quarreling? You always keep an eye on the adjustable mirror. Mount it on the rear window if your child is sitting in a rear seat and on the windshield if your child is looking forward. You fix the mirror with the suction cup on the window or with the clamp on a sun screen.
