Query: Very Expennsive and Very Lousy Performance!

Got this radar detector and had high hopes for it because of the GPS and anti false alarm sensitivity.Unfortunately in my first week I got a nasty speeding ticket. The officer had a laser gun and it didn't warn me until it was right in front of me. With this kind of protection who needs protection at all?Sure the slim unit looks great, and I like the talking radar but at the end of the day don't you buy this to avoid tickets? My friend swears by his Valentine, which looks ugly, but really who cares about the looks of a radar detector.
