Laser Jammer Woes
This isn't uncommon. Few installers understand the differences between lidar and radar technology. Many assume that a laser beam passes easily through plastic, just like microwave radar.
Laser jammer kits include bubble levels and directions for alignment, both frequently ignored. Jammer alignment is critical since the pinpoint light beam is dueling with a similar pinpoint beam transmitted by the laser gun. If the jammer can't spot the incoming laser beam, it does nothing.
But I routinely see installers aim laser jammers into the ground; many splay the jammers toward the outside, like they're adjusting the beams of driving lights.
The labor required for a proper installation is considerable. I've spent two days installing front and rear jammers on a Porsche 911 Turbo, for example.

Routing wires through a packed engine compartment into the interior is an art form. So is protecting everything from exhaust plumbing that can glow red-hot at times.
Regardless, plenty of folks spend big bucks on hardware and then shop around for the lowest bid on installation.
And I have yet to see an installer road-test a finished system with a speed laser. No surprise considering that $3000 police lasers can't be found on the shelf at the local Walmart.
Small wonder that many jammer-equipped cars prove to be no match for laser-toting cops.
