Review title: Very disappointed
Product review: I bought this to help monitor my daughter while driving. The system is very difficult to install, you need two people, one to sit and look in the mirror, and one to adjust the rear mirror. I used the remote operation and the light stayed on the whole night and wore out the batteries. This system sat in my car for a year and never once was useful for me, don't waste your money on this.
