K40 Laser defuser proven to be uneffective. This system cost $300 and doesn't jam any laser guns like it says. This jammer is extremely outdated. Laser Jammers that actually do jam laser as described would be: Laser Pro Park, Anti-Laser. Also look for jammers like the Blinder M40 and Escort Zr3. The later 2 jammers performance isn't the best but it has been enough to save people tickets in the past and is alot better than the K40 system.

  • Get a new diffuser, they do work, yours must have been screwed up, there are other videos posted that shows it works very well. I wish K40 had posted their test .

  • @timmhaines

    So you are going to trust the company who is selling the product to give the actually results... :rolls eyes:

  • Mustang is still trying to comment that the K40 is the best but I still have yet to see a K40 detector that has beaten any Escort, Beltronics and Valentine detector. Also this jammer is proven multiple tines to suck!

  • YOU HAVE TO TURN IT ON lol jk i had one and it didnt work either...tryed it with the signs that tell you your speed and they always picked me up.

  • It was on. Look at the E04 the jam code on the stalker LZ1. I know a guy organizing a testing event for all laser jammers both in central upstate, ny and on Long Island, NY. You are welcome to come and show me and him a working K40 defuser.

  • I love how mustangwner2003v6 still swears by the K40 hahahahahhahahahha

  • They will sue anyone that shows the true performance of their shitty products! If they performed as advertised they would have no problems with people testing them.

    K40 = dog shit!

see all

  • I have a K40 with diffuser. I never got a ticket & the system consistently identifies threats FAR in advance. Here in NYC and LI the cops and troopers don't use any laser so it is the radar which is important to me but many trips up the east coast also identify threats and show no cops up north or northeast use laser either. Maybe it's a different story out west but it's a good buy for the money here. Good integration.

  • Actually the Laser Atlanta is Stealth mode is just slower to acquire speed readings the only thing it briefly jammed was the Stalker LZ-1 which displayed E-04

  • who cares if it "doesn't" work they will pay for any ticket you get for the fist year so obviously they have something that works.

  • Interesting that Other companies recommend 4 jamming heads on a vehicle that size. I haven't used my K40 in a while due to the new laser guns out. Knowing this I did call the company a while back, and they will upgrade the firmware for the new guns. When i did use it a couple years ago it worked GREAT. As you saw briefly with the LA non stealth mode it did jam. A firmware upgrade to handle that and you are set. But honestly how good do you think 1 head would work on that SUV.

  • K40 was invited and they declined. I talked to the video originator and they told me the exact details on how K40 then tried to sue them just for testing their product
