I have a Bel STIR Plus. It has the shifter paddles which are the jammers and I have those front and rear.
After 75k miles and 4 states over the last 2-3 years, I have never been pulled over for speeding.
imho, it is the best one out there. I hear there is a newer system that is better but I cannot remember the name. The 'better' aspect is that the newer system (not sure of hte manufacturer) uses an algorithm and not a database to jam laser. However, in TX, Kansas, OK and NM I have never had an issue with my STIR Plus being outdated. OK, I just looked up the 'better' jammer and its the Antilaser Priority Laer Jamming System. I do not have it, so I cannot claim personal experience.
My STIR Plus has a gps system that alerts to speed traps and red light cameras (I never run red lights anyways), it is absolutely stealth and does not hang on the dash. Plus, it jams.
I have no kickback or financial incentive and I recommend checking out radar roys website.
I've got an STiR Plus radar detector. It's a very good radar detector.
I went with the radar-mirror display which is super cool. It makes the detector completely stealth install.
The laser jammer upgrade that they offer on the Bel & Escort (same company) detectors is not very good compared to the competition, however. I ended up getting the Blinder HP-905 jammer which consistently has tested better. However, even the Blinder is considered obsolete now.
The best laser protection on the market currently is the Anti-Laser Priority. It is the 1st jammer that can jam the newer variable pulse rate laser guns like the Dragon Eye.
There is a new entry to the market called Stinger VIP. The initial reports are very good on it. It does both radar detection and laser jamming. The radar sensor is a patch antenna which is completely different technology than every other radar detector previously designed. The range is even better.
The laser jammers are also very small and easy to hide.
The Stinger is crazy expensive, however. About $3000-4000 for a basic system with front protection only, and that's before installation cost.
Currently trying to decide which system is going into my Mercedes. It's either going to be a Bel STIR Plus with Anti-Laser Priority, or I'll do the Stinger VIP with Fiber Optic laser jammer (front only).
