Well, I think my mom's Bel Express 925 crapped today. Bought it for a Christmas present for her. Started randomly alerting on Ka with high signal strength. Seems to quiet down after it's been on for an hour or so, but it's simply us-usable before that. It still seems to detect real signals too. What really puzzles me is that this is the same thing that happened with my old Cobra 9870. Signal would shoot up to 3 or 4 on Ka then it would go quiet. Only difference is that it seems to happen a lot more with the Bel. I'm giving it a try in my car, but not putting a lot of faith in anything good happening right now. I've already got a return # for Bel. Is this something that happens a lot with cheapo detectors like those or am I just hated by the detector gods?
