  • Red light camera works!

    I purchased this to replace a radar detector that would not work anymore due to the fact that it was left in a very hot car during the summer. I knew where a red-light camera was located and this detector picked it up right away! I have learned my lesson to bring it in the house during extreme temperatures. Also, we had a thief in the neighborhood that was breaking into cars. Bottom line, bring it in the house when you park your car!

  • 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.

  • Falling Apart

    It cannot handle the heat. I leave it in my car attached to the windshield. It has been about 7 months and the LED display no longer works. The voice no longer works. The only thing that works is the beeps!!!!

  • Lasar detection doesnt work.

    I got a ticket today for speeding and the cop was in the middle of the road with a lasar gun. Not one time did this unit detect anything. So now I have a worthless unit and a $200 ticket thanks whistler
