Good cheap Radar Detector / without the bells and whistles u never use
Ok, this is my 2nd "Cheap" (read below $50) radar detector. The earlier one was from Cobra (very good too). I'd planned to get the same model for my wife's car as well (she recently got a ticket :( ). But while browsing Amazon I came across this model, good / cheap / functional. What i liked was the "Blue" indicator lights (really cool at night) and the visual signal strength meter.

Both are very similar, however for $5 more the Whistler is a little bit more sensitive (both give u enough time to slow down). However the audible alerts on the Cobra are more pleasant... u know the tonal quality and stuff. The whistler audible alerts are very harsh... and if u live in a city zone like me.. that means constant irritating noise from the harmless radar doors, safety radars, etc...

Otherwise, the cobra is smaller (+1 point). Whistler has longer cord (+0.5)

Overall both are good and for under $50 each, I'd say get one of both yourself. Good investments against tickets / insurance rate hike...

Other than the audible alerts, I like the whistler better though :-)

Hope this helps.

Very good especially for the money
The product was shipped on time and performed much better thean the price would indicate

Good product
Best value of money.
warns you every time there is a cop with a gun!!
Though it keeps warning you very often which is annoying

Good for the price
Had it for a couple of months and am very happy with it. It has regularly picked up police radars long before I spot them, even behind hills (luckily I live in Florida so not many of those to contend with!). The laser detection is fair also. Compared it alongside a V1 and the difference is barely noticeable - the V1 beeps maybe a half second before the XTR did.

Some minor complaints: It gives out TONS of false alarms, especially when I'm driving around town - OK so it's a fun geeky thing to know when I'm half a mile from an automatic door, but still it drives my SO batty when she's in the car! The VG-2 detector appears to give a lot of false alarms (unless Florida law enforcement really do have them scattered every few miles, which I doubt) but it's disabled by default so no big deal. Finally, I would have liked either to see a separate Ka indicator or have it blink on K band detection instead.

Whistler XTR-140
Had a Whistler for years, replaced it with this one. Just as good if not better, why spend more? Do a lot of highway driving and never got a ticket. Gives a good honest warning within a mile or so. Just remember when you drive past a cop, they dont always have their gun on. So dont blame your detector. I really like the blue LED's they warn you visually when your radio is turned up. Overall i would recommend this to anyone on a budget or needing a unit for a second vehicle.
