Let me see if I can put it as politely as possible......I had (well still have in it's box) one of their jammers. Um....facts, reminding myself, ok....part of the case itself melted in the sun down here in Phoenix. I've had Escorts, Passports, Beartrackers and of course many Valentine ones mounted in the upper windscreens of cars and never had anything melt, except of course for one. The test that one of the big three car mags did (Car and Driver/Road & Track or Automobile, don't recall exactly) showed this jammer wouldn't work on a bicycle with a 12V battery on it to power the jammer.
I sure hope their detectors are better.....
