Ok for starters I saw how the M45 performed on RacerX's video, the only time he got instant PT was at the edge of the headlights where the sensors could not detect it.
my post from rd.net:
someone linked me to this. The video maker claims it is an m45, but the bottom two heads are fake. This causing punch troughs at long distance when they aim at the plate because the other sensors don't detect it. Also punched through when barely off the edge of the headlight which could have been avoided with better head placement im sure.
Blinder Xtreme Laser Jammer Tests & Reviews
You can tell when they aim near the top sensors it jams. At long distance, the LED's do have issues reaching im sure which causes some punchthroughs due to the cars massive chrome grill reflecting well. But most of it has to do with the missing two sensors and the worst IR reflective profile ever.
I think alot of peoples speculations that blinders are not crap, because it clearly is doing its job when they aim near the sensors that work. Sure it may not be a diode jammer, but it is much cheaper than them.
Someone is trying to make blinders look really bad, when in reality it looks like a pretty decent jammer for the money.
