Beware - defective product, poor response from Bel

Purchased from Amazon and has not worked in Ka band since new. No alarm passing traffic boxes that display speed, or patrol officers using Ka band. I received two tickets from radar patrols, one only a warning, thankfully. Also, if left in the heat, will display "service required" and not work until it cools down. Betronics people trained to provide lame excuses; claims Amazon is suspect retailer, may have re-packaged defective unit as new, traffic boxes not calibrated or don't use radar. Made me pay another $59.95 to get repaired even though it has NEVER worked, right out of the box. Even though using two detectors in a car is not advised, I ran this unit side-by-side with my 15 year old 9500 Passport and the Bel remained silent as the 9500 alarmed in Ka mode. In all other modes, it performed as well, or better. I didn't know for sure that it wasn't working until I performed this test. Until then, I was believing the Beltronics BS. By the time I returned it, I was one month out of the 1-year warranty. One final note, it will give a continuous laser alert if you are driving into the least amount of sunshine. Is an excellent sun detector, not sure if really detects laser or not. I just got off the phone where I informed Beltronics that I would write this review in response to the way they handled my return of this defective product. Hopefully, after paying a traffic ticket, increased insurance, and an additional $59.95 to repair, they will return a working unit to me, but I will never trust it. Although they are now owned by the same company, I should have paid the extra money (actually much less than this has cost me) and bought a top of the line Escort.
