The Cobra XRS 797 Radar Detector is an exellent product. I bought 2, one for me the other one for my brother. Buying from Walmart is a great deal. If you compare the price with Cobra's site, you'll save alot of money. I've been using it for a few months now, and it works great. The suction cups work well, and don't drop off. I am very happy with it, and hope it continues to satisfy my needs while driving. Also, the voice alert is such an added benefit. I can hear it clearly while listening to the radio, or with the windows down. I definetly reccommend this Radar Detector.
