This is an auxiliary mirror that allows you to check on a baby in the back seat from the driver's seat. It was a great help because I could see how my child was doing at a glance! I used it for about a year after purchasing it. Since it was only installed, it can still be used. It will be disinfected with alcohol before shipping. * Please note that the box will be discarded here due to shipping costs. Please purchase only if you understand that this is a used item. No pets, no smokers.
