  • Great Radar

    I purchased this product because it had more features than my old one and it warns you of red light cameras. Ive had it for almost 2 weeks and I love it. It also has a clock and arrows for the compass. My husband saw mine and wanted one so i ordered another one. My mother in law also ordered one. It is such a great product, and for the price. I highly recommend.

  • Horrible Acts Up

    1) The volume is the same regardless of the volume button2) The mute button works for mere seconds3) The time was correct until DLS. We went back an hour and the device clock went ahead 2 hours. I turned off DSL and it was ahead 1 hour. I had to remove the clock feature4) All the radars go back n forth from 1-9 regardless if an officer has radar on, which I have verified while talking with officers at their cars.5) Emergency Vehicle warning doesnt work for EMS/FIRE.HSN refused exchange
