Cobra XRS-9930 in use
597518
purchased this detector for 12 hour drives through 4 states I make about 5 times a year.  Amazon's price was great and I did not expect this unit to compete with others costing 3x or 4x more.  When mounted high on the front windshield, it has "OK" range - not great - but OK.  It receives all the most common law enforcement radars in use today, but when it sounds off the transmitter is not all that far away - trust it and slow down for anything other than an "X Band" alert (I will probably turn that off in the menu )  I really like the auto volume control where it will turn down the alert volume after the first alarm - you don't need to listen to the beeping alarm at full volume.  The voice announce of the type of radar is good also, you don't even need to look at the unit display to know what type of radar is being used.  I hate the short curley power cord....made my own out of straight wire (Cobra sells one, but I'm too cheap).  Good unit for the price !

Cobra works great. This newer model seems to have a further reach than the last one i used. Pays for itself the first time it helps you avoid a speeding ticket.

Battery went dead on my BMW X5 (E70) and with my other car being a hybrid (Prius) it left my jump starting options limited. I went on to Amazon and found this gadget and had it delivered the next day.

I was worried that a power pack the size of the Cobra (it's a little bigger than my iPhone with it's case on) wouldn't have the juice to jump start an SUV that apparently has a large battery. It worked like a charm the first time I tried it.

I'll be keeping this in my glove compartment from now on and wouldn't hesitate to recommend it to my family friends. Might even buy a few more for Christmas time.

I've had this since Aug. 09 and have been very happy with its performance.  I use it on a stationary bike in my basement. It comes with a gizmo that allows you to mount it (the watch) to the handlebars on the bike. In the old days when I used the much overpriced Polar I had to use double sided tape to mount it.

The other thing I like about it is that u can replace the battery yourself on the transmitter (The part that attaches to your chest). You simply insert a coin in the slot on the back of the transmitter and remove the quarter sized cover to gain access to the battery. It uses a common type of watch battery available at Radio Shack, Best Buy, etc. With the polar u had to ship the whole transmitter to them and they had to break the harmetic seal and replace it. This is not cheap and the batteries only lasted around 12-14mos. Not to mention the delay in recieving it back from them.

I highly recommend this product for its performance, convenience and reasonable price.

Below is the exact model I purchased. Go ahead and click on it for more info:

I originally purchased a cobra dash cam and was unhappy with it I returned it and bought this one.  I am very Happy with it.  Works well and a good price.

This is the first radar detector I have ever owned, so I have nothing to compare it. Hopefully my cross country experience will help someone.
I was driving cross country and decided that I needed some insurance in case I was careless and sped through the wrong highway. I purchased the Cobra XRS9370, largely because of the price and the reputation for being a good budget detector.
The route I took had me going through Virginia, West Virginia, Kentucky, Missouri, Nebraska, Wyoming, Utah, Nevada, and finally Calirfornia.

I started out in Virginia, but did not turn on the detector until I hit West Virginia (legal issues), and found the Cobra to be spot on in West Virginia seeing cops stationed around a bend in the highway. It also found the stationary speed traps that show you how fast you are going well before I saw them coming.

The trouble came in Wyoming (or Nebraska, they kinda bleed into each other driving wise) when I would receive Pop alerts and there was basically no one around. I would also receive many false K-Band alerts, many meaning every 12 seconds. This would continue until I hit Utah where they would still happen but not be as frequent, maybe every half hour. The thing is when these false alerts would pop up I would be alone, in broad day light, with nothing for miles and no where for cops to hide. I was going around 95mph in certain areas and brought no attention to myself. There were legitimate times where if there really were a cop with a radar gun I should have been caught because I purposely sped when I heard the alerts just to see if it was accurate (Dumb I know, but it was a worthwhile test of the equipment).

My settings throughout the trip were set for highway mode and intellimute turned on.

This is the only time I used this detector since it's illegal to use in Virginia so it's a little hard to judge it's score. In some states it worked fine, in some others it went bat s*** crazy. I will try it on a trip to NYC and update this review and maybe play with the settings more, but for now it is a 4/5 cause it did save me from a few tickets in certain states.

Really handy to have a record of your driving or in reality what happens in front of your car when you are driving. Easy to use, very wide angle of view, Cobra quality, you can't go wrong with this.  Screen size is just right to let you know the camera is working.  Note the power cord is very long on this so you shouldn't have any problem placing the unit in your car.  It is a very nice small size and the camera is easily adjusted to point where you want it to.  Memory cards are cheap get a 32GB micro SD card  one when you buy this for longer recording time.

We purchased two sets of the Midland GXT-400 handheld transceivers, and have been quite happy with them.  The receive and transmit audio quality is pleasant and clear.

Their range performance is comparable to the Cobra PR-4000 series radios.  Receive sensitivity and transmit power appear to be about the same.

The Midland GXT-400 has a smaller profile than the Cobra PR-4000; this makes it easier to carry and use, but may adversely affect effective radiated power output.  However, it does not have all of the "bells and whistles" of the slightly larger Cobra.  It has a NOAA weather radio included that is not exceptionally sensitive, however it is servicable.  Unlike the Cobra PR-4000, it does not include a NOAA Weather Alert function, receive signal strength meter, stopwatch, clock, alarm, directional compass, etc.  Of course, the Midland also is less expensive than the Cobra.  I personally like the "bells and whistles" of the PR-4000; but for those who like a radio with the important features that is simpler to operate, the GXT-400 is a joy to operate.

Please be aware, neither the Cobra nor the Midland will attain anywhere near the ranges claimed by their manufacturers on their packages. Using a pair of GMRS handhelds in our residential neighborhood setting, we usually get a reliable one mile range,  spotty coverage out to about two miles, and periodically around three to four miles from high points in the terrain.  (Coverage area can be significantly improved when communicating with a base station using a commercial quality transceiver with high quality feedline and a good antenna placed above surrounding obstructions.)

All in all, I am pleased with these radios and would recommend them.

Design and function are much better than Cobra. Especially the range is longer with Motorola EM1000R. I use it for hiking trip to Angeles National Forest, Yosemite, and San Jacinto Park area. When used with several, meaning with more than two persons and each person with their own EM1000R, we can easily relay the signal and repeat the message down to the last person at the end. Thus, the range and capability is proven for 16 miles round trip trails for 40 members with about 10 Motorola EM1000R amongst the hikers every week on the trails. I highly recommend this over any other products for two-way radio communication.

All the performance up grades I've done have been 1  part of the total effect on the bike. First I put on less restrictive exhaust, then new header pipe and k&n filter then I put on the cobra FI 2000. It is a total different bike in how it accelerates and runs. No more lugging the motor, I'm totally satisfied with it, the tech support was excellent as well, I had a few questions and they  were easy to contact and gave me the information I needed.

Perfect! Have a 99 and 01 xr 100. Literally started first kick and runs like new. Just ordered 2 spares.

I usually purchase either a Whistler or Cobra brand because they are in my price range.  I googled radar detectors and found a comparison with the $300.00 & $400.00 brands. This Cobra 9670 was rated right up there with the best.  I find the Cobra easy to program and the instructions tell you a little about each option that you have on the settings.  The compass does not seem to be right on, but it may be that I have my GPS next to it when I calibrated it, so will clear my dash and see if that helps.  Over the years the Cobra has saved me many a ticket.  One just has to remember that if you are the lead car, you don't have much chance of slowing down when the radar detector goes off.  I always try to have a vehicle in front of me, so that I am warned of a radar ahead. I have a Cobra in my wife's car also and it has saved her a time or two.  They pay for themselves in one avoided ticket! I like the power saver mode, so if left on; one doesn't have to worry about a dead battery in the morning. For the money, this is a good purchase.

The Garmin Foretrex 401 was a gift to my wife for equine competition.  She is very please with it, from the small size to its accuracy.  Battery life is also a plus.

I know, I know.  We're all supposed to hate Cobra products and only buy 600 dollar radar detectors.  Well...yeah.  I'd like to be able to do that, but unfortunately, I can't (yet).  So I saw this on "sale" (you always see this one advertised at $189.00 and marked down to $59.99) and bit.

I have to say, I'm somewhat impressed by this performance.  Yes, you get tons and tons of false alerts.  That doesn't bother me, really.  I've used radar detectors for years, so I'm used to the noise.  Besides, in my area in a more rural area of upper east Tennessee, a lot of the city police are still using K-band radar (and believe it or not, the Tennessee Constables around here are still using X-band!), so I have to be aware of all of the alarms I get.

I have been fairly impressed with the range of this unit.  I've picked up blips that I assumed might be false alarms, only to find that indeed, 3/4ths of a mile away is a police officer.  Ka pick-up has been very good so far.  I'm not talking the performance of miles away, like you read on some of the reviews of the Escort products, but I think you'd have enough time to make necessary changes before you're seen by the officer.  (Did you know that all Ka alerts are real threats?  There are no false Ka threats.)

The other thing that I do like about this unit...it looks like your GPS!  I think stealth is a big factor in using a radar detector, and besides the price, the whole reason I bought this thing was because it just doesn't really look like a radar detector.  Yeah, it is bulky, like you see a lot of reviews say, but if an officer pulls up behind you, at first glance, this is going to look like a small gps on your windshield.

I generally keep my screen brightness turned off.  You'll soon get used to the different audio alerts (additionally, you'll hear a few beeps, then a voice saying "K-A Alert" so you dont' really need to see the screen).  The screen information is stupid, anyway.  There's a constant readout of the voltage your battery is putting out, and an annoying green light that moves from side to side.  It's like the engineers had this great screen, but no real good ideas as to what to display on this screen.

I'm generally happy with the performance of my detector.  It doesn't have POP alert.  I've not been through an area where a traffic officer is using LIDAR.  But I like the range, and the way this thing looks, and until I can save up for a more advanced unit, I'll keep using this little guy.

I chose these for the cobra reputation and excellent specs.  These were just too big for my requirements. I'm glad they arrived in clear packaging so I didn't even need to cut it open to see the size wasn't right for me. I appreciate that they accepted them back unopened and refunded promptly.

I really like these pedal. Smooth, tight, well built. I owned some 2000 ish iron cobras, imo these beat them hands down. Like the clamping system on these, very easy.

The radio works great. Took out a uniden flush mount, and the cobra slid right in the same hole. Simple install
