I know a few people here at NEJeep have the Cobra 75 WX ST. A few people warned me before I got it, but I got it anyway. Waist of money for me. I am glad that it has works for a few, but for me, it crapped out in 6 months. There is a set screw down at the bottom, that often falls out and when that happens it twists the wires inside, and can only be fixed by a good tech. Also, it was heavy, got in the way, and when you are fumbling with it, you accidentally push the buttons. With the top down, I held it to my head when someone would talk and it would change channels... etc.
I am on my 3 unit, and the one that has lasted the longest is the Uniden I got from Walmart on a trail ride up in North Adams. Nice small mic that I have beat the crap out of, put an external speaker and it sounds sweat. I always wanted a nice high end unit, but they can get $$. But worth it.
