I own a Valentine 1 and an ****** SRX.
From using them both for more than a year, and using them both in the same car for a month (so I could compare them), I can tell you first hand that the radar detection capabilities of the two are so close as to be almost identical. Don't believe any magazine or advertisement that tells you that there is a difference in radar detection range. It simply is not true.
So . . .
Here are the differences:
Valentine 1 has directional arrows that tell you where the radar is coming from. This is very useful.
The Valentine 1 mounts on your window, with a dangling power cord.
You can easily move the Valentine from one vehicle to another.
The Valentine 1 detects radar, and sort of detects laser (but not very well.)
To mute the Valentine 1, you need to press a button on the detector unit itself.
The Valentine is a lot cheaper.
The ****** SRX doesn't mount on your windshield. The radar detector node is mounted out of sight behind the front facia. There are two laser jammer/detectors that get mounted on the front of your car, and one laser jammer/detector that mounts on your license plate bracket. The controller box goes inside your car. The box is small. about 1/2 the size of a pack of cigarettes. Installation of an ****** SRX is not a do it yourself job. When installed, the system is very discreet. There is no dangling power cord, and no detector on your windshield.
The ****** can't be moved to another vehicle.
The ****** has a seperate mute button that you can mount anywhere, so it doesn't have to be mounted on the control box.
The ****** detects and jams laser. This is the only real defense against laser, because laser is virtually undetectable by any means until you are being targeted. The laser jamming is very effective. I know from first hand experience that it works very well. I don't know what things are like where other folks live, but here in Colorado, laser is becoming the tool of choice for the highway patrol.
The ****** picks up highway safety broadcasts (not super useful.)
The ****** is very expensive. Plan on spending about $1300 for the device and installation.
As I said, I own both. I have the ****** installed on my Viper, and the Valentine gets used on my other vehicles. I like the cleaner look of the ******, and the laser jamming is invaluable. I would have received at least 4 tickets in my Viper if i did not have laser jamming.
Both are good units, but if cops in your area use laser, I would spend the extra money on the ******.
If you look closely, you can see the laser jammers mounted in the front facia:
