Query: Puts your mind at ease

I don't know how I would have been able to stand having my son in the back seat and rear-facing without this. The fisheye mirror lets me see him from the top of his head to his little feet, and there's really not that much distortion. He also likes to talk to the animals around the mirror. I've installed this mirror in both a small sedan and a station wagon, with no problems - there is a tether that lets you clip the mirror to the anchor you'll use when you turn your car seat front-facing, as well as several other installation choices.
