Dude, my Uniden from Goodwill still work great. I got it in 98 right after I got caught for speeding trying to pass someone. Ever since then, I've never had any trouble w/ pigs for speeding. There are times that I got lucky, but most of the times, I watch for them. Anyway, my Uniden detect 360deg. w/ X,K,Ka, and one other band. For 3 bucks, it's well worth it.
