Who's the joker who gave this a 1 star review? My experience with this item is a 5 star one. Here are my thoughts.

Pros:

Scans for so many types of detection K, X, Ka, VG2, Laser... I've seen them all go off in just a few days. I had no idea there were so many cops around!

alerts you in order so the most advanced speed detection system is prioritized over the lower ones.

Detects signals from cops I can't even see and I'm on a motorcycle, so I'm taller than cars and can look in all directions. So, basically it's picking up signals from a few blocks away.

gives you signal strength of radar etc from 1 to 9 so you know if they're right up your ass or a few blocks away AMAZING!

legal :)

fits to my screen easily with the enclosed suction attachment. Was a bit nervous about it falling off but I've been over some major bumps and so far all good.

-contrary to the 1-star fool the batteries that come with it last a good amount of time, as do my other rechargeable batteries that I use with it. Don't know what he's on about.

display is bright and easy to see

flashes an 'all-clear' when the signal goes away.

Cons:

errrmmm... racking my brain to think of one... my only addition would be a headphone socket so I didn't have to rely on glancing at the display (bit loud on a motorcycle to always hear the voice forget it on freeway).

Case-study

I was a little dubious before I bought this that it would work, but it really does. I tested this on day one by flying past a stationary cop in traffic. Sure enough he starts to follow me. I cruise at the speed limit and within 10 seconds I am alerted the exact moment he switches on his radar gun to track my speed. I ride on. Since I did nothing but obey the the law and speed limits, after a mile or so he gets bored and peels off. System gives the 'all-clear', and away we go. I couldn't ask for more for what I feel is a very reasonable price a just under at hundred bucks. Get one! :)

Like the different filters to tune out traffic sensing radar. Seems pretty sensitive to real radar from cop cars. The vg2 went off a few times already. You have to keep in mind that when vg2 is detected the local oscillator In the detector shuts down for 30 seconds to avoid detection by the cops. So even though it shuts down of corse u know there are cops around. It's a keeper.

I have owned two other Whistler radar detectors and the XTR-445 is much more sensitive than the others and the ability to use it without the power cord is the main reason that I bought this model.

Seemed to work great, would detect radar with more than enough time to slow down, about the same range as my old Passport. Didn't seem to have any more false alarms than my Passport, in fact there were a couple spots on my daily commute where the Passport would false, but the Whistler would remain silent. This was using the Highway mode on both. They don't use Laser around here luckily, so I can't comment on that.

Batteries seemed to be good for about 5 hours before they would read 25% left. That was good enough to last the week for my dailt commute to work, but if it sat unused for 2 days after re-charging, it would drop to 75% without ever being turned on, dropping the life to about 3 hours. Not great for any trips, don't forget the cord, or some spare batteries. I had planned to replace the cheap chinese batteries with better quality rechargeables to see if that would extend battery life.

Got in the car yesterday and turned it on, it goes through the entire test sequence, and then says "NO BATT" and shuts itself off. How can it turn on if there are no batteries? I tried charging it overnight, even tried a different set of batteries. Same results.

JR is paying return shipping to exchange it, so I will try another. Hopefully it has a longer life span. I can highly recommend JR music world, great service.

UPDATE 9/11/2012: I received the replacement from J&R a couple of days ago. The batteries that came with this one are garbage, and will only run the unit for about an hour before the charge runs out. I have tried regular alkalines (DO NOT charge these!) and it shows 50% battery life after 8 hours. I have some Eneloops on order to fix the low battery life. Just a warning that if you do buy this unit, plan on replacing the batteries right out of the box.

I was very satisfied with the way it responds so quickly to any detection. The only negative thing I have to say about it is, the battery life does not last long at all. I can get about an hour to maybe an hour and fifteen minutes use out of it before the low battery beep goes off. Other than that, I would highly recommend this product to anyone looking for a good, yet affordable radar detector.
