Wonderful Modules and Customer Service I have to say ... the ST2 Systems is great. I made a wrong order and got the breaking Modul instead of the strobber. It was entirely my fault. Nevertheless, sending an email was enough to get a response that I didn't think possible. I can keep the breaking modul and they sent me the strobber for free. That's on hell of a customer service. I whole heartedly suggest you try them. Mduls work very well on my XVS 1100 Dragstar, btw :-) ... Very happy

Brake unit too sensitive! I ordered this from NZ, took about 3 weeks to arrive, no problems there. Fitted correctly, but I've found the sensor is much too sensitive. Brake light flashing almost continuously even though I've installed with the wires very high as instructed. I've had drivers pull up at he lights to tell me my brake lights flickering almost non-stop! I've disconnected as more dangerous than not having it.

Horrible Device The device constantly activates just from the vibrations of the bike. Does NOT work as designed and is more of a danger than any kind of assistance.

THIS DOES NOT WORK AS DESCRIBED THIS DOES NOT WORK AS DESCRIBED, FLASHES brake light when accelerating =, going over road bumps etc, no good. I had 2nd unit sent to me but it was the same, had to claim through paypal as they will not reply to my emails after 2nd module ws posted, AVOID ITS GARBAGE

same as other users do not buy same as other users, comes on when accelerating and hitting bumps flashing all over the place. keep resetting angle which is a nuisance, then doesnt work at all so reset again but still dose not work flashing when it feels like it. Dangerous, wasted hours of my time. throwing it out now
