Today about 20 minutes ago I was driving and my Blinder M45 started to alert. It continued this alert for about 10 minutes before I got home. When I got home I figured out that one head when unplugged stops the alert. I believe this head has a short of some kind on the inside. How good is blinder at repairing these and sending them back? How long does it typically take? I'm very annoyed because I spent almost 700 dollars on the things only for one of them to just stop working after less than 3 months.
