Query: Do not buy! Will fail extremely fast and cost you more!

I bought a Beltronics 995 just over a year ago. I went on a trip last week and the unit started showing KA band the entire time. I tried to unplug the unit and then turn it back on and within five minutes the KA band will come back on and just continue to beep for hours on end. I called Beltronics and they charge 60 dollars just to look at it. This unit has never been abused. It sits on my windshield of my truck and is parked in my garage! I could not believe how terrible the customer service from Beltronics is. To pay 300 dollars for one of the "so called best" units and have it only work for a little over a year is unacceptable. I am warning everyone out there not to buy this product. Yes it worked great when it worked. But you will not be satisfied with how long it lasts. I am extremely meticulous so don't think this unit was thrown around.GO to a different brand all together than Beltronics!!!!!
