Any one have results w/ Laser Star?

I'm looking at the Passport 9500CI, but have heard that the ZR4 laser pieces don't fare well w/ Stalker laser guns which my state uses.

Also if I was to buy the Laser Star or another set-up would it hook in directly in place of the ZR4's supplied?

Or would I have to connect each system separate?

Hope these aren't real dumb questions, I'm new to the jammer stuff.

Currently I use a Bel STI, but want better protection.

Any other system reccommendations are appreciated.
