Don't get the M45 for the bike....it is a feaking waste of money. (not the jammer, but that many jamming diodes) get the M25 and that comes with 2 jamming diodes. You don't need 4 with the M45. Yes, they do work.....I know first hand and personal experience and used them in the real world. If you have them installed just always leave them on. Don't bother ever to turn them off when you see the police......you are on a bike.....they are not hard to install......I have had the state police hit me with laser and get nothing and than keep trying to hit me. How I know??? I have a radar detector on and it was saying laser and I can hear it through blue tooth helmet with a bluetooth transmitter on the radar detector. In April I was in Georgia flying like 110 MPH over a bridge and the georgia po po was on the other side....hitting me with laser.....I let go of the throttle and went right by him....he never bothered me.....I use them so I don't get speeding tickets.....they are useless with KA radar....only when they are shooting laser. Place one under our bike in the front with construction grade velcro and than I use Monster Tape as a backup for the laser diode. Just check the tape every once a while and peal tape off and re tape it....your good to go.
