Welcome to the forum. There are many radar detectors to choose from. However, most radar detectors are worth less than the packaging they come in.

The more expensive Whistler radar detectors are good for those dirivers who do not exceed 10 miles per hour over the speed limit. They lack the range that one needs who drives significantly faster than the speed limit. The only windshield mount radar detectors that I trust on my windshield are the Valenine 1 and the Escort Redline. The next tier of radar detector are the Escort Max, Escort SmartRadar, Escort 8500x50 Black, Beltronics STi Magnum, and at the lower end of this tier the Beltronics Pro 500 and Pro 300. The high end Whistlers are in the next lower tier.

Feel free to ask questions. The only stupid question is the one you don't ask.
