rocky mountain radar jammers are a scam. check out some reviews and check out the courtcase they were involved in. at one point they had one device that actually did jam one frequency...k i think. but it didn't work that well.
if you really want a high end detector, go with the valentine 1. it's supposed to be one of the best. front and rear sensors with the capability of detecting the distance and position of the oinker.
now everyone squeal like a pig...weee..weee..wweeeeeeeeeeee....
