I was extremely skeptical about the performance of a $40 detector, but after a few recent road trips, I am convinced this is actually a well functioning product. Although it does not have exceptional filtering ability for false signals, it can still give you enough X/K/Ka warning for you to slow down in time.
The two blue LED's are a great innovation, because you can easily see them out of the corner of your eye. This is extremely useful when your radio drowns out the audible signals, or when the sun washes out the primary letter warning lights.
You simply can't go wrong with the price. It does not have the features of the top of the line detectors (coiled power cord, voice alert, text readout, settings save, compass, etc), yet it has at its core the most important feature: the basic detection ability to provide enough warning for the driver.

i purchased the xtr 140 and it has been great so far, from what ive read the 330 has voice alerts and thats the only main difference. higher end radars have alot more features (compass, volt meter, aarows, pop detection etc) but none of that matters to me, i just wanted a radar detector that works. usually i find myself drifting 12 or so mph over the posted limit in the city and it gives me plenty of time to stop. besides a blip of ka when i pass a walgreens or cvs (if you are pointed at the doors its a full alert) the city 2 mode is pretty quiet. then again i can barely hear the radar when it goes off with the radio on so the lights come in handy to get my attention
i bought the 140 model because it was cheap but still accurate. i really dont care about a 3-4 mile range of detection because with instant off and instant on even a v1 cant save you if you are alone on the road. no one uses POP radar and im not going to pay another $50 for a feature im not going to use, and in the city there are so many cars on the road that i can pick up a trap in more than enough time to react.

i have had this detector for about two years now and it has yet to disappoint me. however after owning it for about a year i felt the need to splurge and purchase a higher end unit, the whistler pro 78 rev c. i thought that my top tier purchase would blow my old xtr140 out of the water, but suprisingly the performance was nearly identical. however with the pro 78 you get to select what functions you want enabled or disabled.
in short i have to stick to my original review
pros:
i have gotten over a mile detection of a K band speed trap
i have also gotten slightly over a mile detection on k/a band
very clear display
VERY cheap
cons:
lacks internal memory. doesnt save settings
"chatty" on k and specifically x band. it will pick up your cvs walgreens everytime. its best to run city II mode if you do heavy city driving
i still recommend this product to anyone when they talk about speeding tickets. always gives me plenty of time for radar alerts
the whistler also has that signal strength meter, where as i believe the cobra does not. i have a cobra esd6060 and this whistler destroys it in detection distance

Nice quality. No nonsense.
Picks up some stray X from industrial parks or commercial buildings occasionally in Highway mode if buildings are adjacent to interstate, BUT these signals easily discerned giving only one bar on strength meter, and a couple warning only chirps.
However, first night out, I had my unit reach three bars, light up the entire display like a Christmas tree, blip the periscopes constantly, basically seemed like the thing was going to implode ("scary"), and then I saw the cop! He was about 3/4 mile away, opposite side of interstate facing me with a victim pulled over, lights flashing.
Caught him a second time while exiting an off ramp in a hotel parking lot perpendicular to me prior to that with another victim! "Big, bad, Dodge Hemi" cruiser, all painted up with intimidating graphics. "Big bad", muscle car, chase car with undoubtedly the latest radar.
All I know is that this little $38 Whistler "smells" his butt a mile away like a geiger counter detecting radiation! He hangs in the same geographic area around my workplace constantly busting people (a real worka"ho"lic), but now I can "smell" him a mile away for $38!
Me like!
Honest reviews on Whistler XTR-140 Laser/Radar Detector with Exclusive Twin Alert
It's almost exactly the same as my old Whistler 1732 radar detector.The only pluses are the blue lights stand out at night,but you can't even see them in the daytime.Also, the 3rd city mode lets you get rid of the X band which almost no police use anymore anyway so it cuts down the false alerts by at least 80%.Worth it, although everything resets everytime so that sucks almost enough to want to buy the next model up.But for now it will work.Also it's way bigger than my old one.Not bad though for 40 bucks.

I recently bought this detector for my wife since she racked up a few tickets lately, and it has blown me away! I have an older Whistler 1545 detector that is pushing 10 years old now, and this one destroys it (even though the old one cost twice as much). The blue lights are a real attention-getter and the volume dial is a treat (something my old one doesn't have one). This baby picks up waaay farther than my old unit. It picked up a county Sheriff last night over half a mile away, over a HILL! It also caught the splash back from one of the automated radar warning signs they park on the highway (the "Your Speed Is__" things). We were coming up to it, it was 100 yards ahead of us facing oncoming traffic (away from us), and the detector caught the reflected radar waves bouncing off the oncoming trucks. Unbelievable. You would expect his level of performance in the $100-$200 detectors, but not from one that was under 40 bucks. This baby is a real gem.
Needless to say, I am buying another one to replace my old Whislter! Highly recommended.
Pros: Inexpensive, easy set-up, user friendly, exceptional performance.
Cons: None yet.
