LPP/ AL head question

[superbuick]

In some other threads, I recall that some users were having an issue with condensation and/or water entering the LPP/AL heads and causing some issues (or potential issues) I may not be 100% accurate in my description but those who are more familiar might chime in. I also recall someone mentioning they recieved a "new aluminum head". My question is, were the heads changed/redesigned recently? If so, what was the reason for this?

Thanks!

This is a concern/problem among EVERY jammer head from AL, LI, LPP, blinder and escort.

The older AL heads were encased in steel and the new ones are aluminum. I've had my AL dual for about a year and a half, had to send the system back b/c one of the heads was faulty. They replaced the heads and updated my firmware, and its been working fine so far. No water problems so far
