Summary: Wanted a cordless radar and this is it! The only problem is that the volume is not loud and can not be heard if you have a radio on. I have driven up on officers and it didn't beep until I was right on them. I am not really sure if it really works. Wish I had bought something else!! Would not recommend this one.
Summary: I wanted a cordless radar detector and didn't want to spend the $350 for the Escort Passport S2, but I SHOULD HAVE. The batteries that came with this went dead the 1st day I used it and it states that they would be good for 15 hours? Also, to use the compass, you have to drive around in circles to get that function to work!
Summary: ...I do alot of driving in my job that i like. However, there are alot of speedtraps, LEO's running Radar, and hiding on the other side of the bridge or in bushes on the side of the road....sometimes in the median....I switch company vehicles from time to time and I needed a unit that i can take with me from one to the other, and I looked for something of reputable quality and great product. That's when i found the Whistler XTR-540!
