I read the most recent review from GOL. I have not had to time to fully study on all the particulars of jammers, but I got the impression that other than for cost, there is no reason to buy anything but the LI unit. I was disappointed to see that the Escort unit performed so poorly. I figured that will all their experience in building RD units they would also be on the top with their jammers - not the case.
So....... Is there anything new coming to market soon that one should wait for before making a purchase?
These units are stand alone and do not interface with the RD right? Just a speaker and switch in the dash? Guess you really don't need more but seems very basic.
