  1. Batteries are an advantage review by Herb on 8/2/2013

    I purchased the battery version to use in my convertible. When the top is down, I can move the radar from the dashboard to the storage compartment. This prevents theft of the radar. A major improvement would be a nonslip material on the bottom of the radar so it doesn't slide around on the dashboard. Better and longer battery life would also help.

  2. disappointed review by Ron on 1/8/2013

    The product will not turn on if not plugged into the lighter. I bought this model for the cordless feature but so far it doesn't operate as a cordless.
