If they never got any help, it's because they didn't pursue it with the LPP's retailers/resellers here, stateside/Canada - either they didn't buy it from these sources, or that they were out-of-warranty. It's just as simple as that. Both of the North American resale sources are highly trusted in their respective communities, and both will honor any such claim. The Canadian reseller, KMPH-Canada, due to its longer presence in the community, has repeatedly demonstrated this ability, and has received many kudos from its members for doing so.

Similarly, KMPH-UK/LPP-UK has taken care of its UK buyers in a similar manner.

And to-clarify: such an error is not a certain sign of "water ingress."

The LPP will also send out such a signal if the unit receives insufficient or fluctuating voltage - either due to installer error or to later-arising issues with the install/vehicle, neither of which can be blamed on the LPP unit itself. KMPH-UK/LPP-UK was instrumental in both tracing this root cause, as well as in extensively servicing an UK member's vehicle for this fitment concern.

Weatherproofing/water-ingress, based on current head design and manufacture - regardless of the jammer - will likely remain a problem. There were long-running threads on the RD.net Forums which discussed this issue from engineering standpoints, and many countermeasures hobbyists as well as automotive-enthusiasts and professional materials and electrical engineers provided their own input as to why the current construction standards and adhesives/sealants used will always render this issue a concern.

Even the trusted Escort ZR3 heads were not - and still are not - immune to this problem.

The LaserStar as well as PASS are an evolutionary design. Currently, it can only be said that initial weatherproofing is better.

However, it remains to be seen whether if these units will continue to hold, as neither has either the miles-on-road nor the time-on-road that the AL G8, LPP, ZR3, Blinder, LE30, or even the LI has seen.
