I have saved up to buy a jammer, I live in an area where they are highly illegal so I need stealth, and I drive an Audi A3 (leased).
Do I get an m27 or laser star:
According to laserjammertests, the star (vs m25) is the best one (and they did a test on an audi).
I need a wireless tool kit; both jammers have the option except the LS has it's own system.
I can use it as a parking sensor in a COP case.
MOST IMPORTANTLY: The laser Star heads fit exactly in my grill which means no drilling it, unlike the m27.
I need performance against Pro Laser 2-3, L.A. R/S, LTI's.
Laser star is simple but it may not be a good jammer therefore I won't be and feel safe. I don't drive very fast (+30 km/h over PSL).. I like the hobby side of jammers.
