I have purchased several products and… I have purchased several products and have had a great experience with the products and service. First was the turn signal module for my KLR 650, which I needed, I would ride for miles before turning them off. Thank goodness it works as it should. Recently I ordered to brake modules. One for my Harley Road king and one for our (Hers) Cam Am F3L Just installed a couple of days and appears to work as stated. Haven't had it out on the road yet. OK, so here is why the best customer service I have had anywhere. I received two Flasher modules instead of the Brake Modules. I emailed about the situation and had a response next day only to find my order was for the flasher modules. My bad. Customer service has sent me a brake module for free! Waiting for delivery now.

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.

Dire customer service and rubbish product Installed on an aprillia RS4, constantly flashing unless unit is near vertical in which case it doesn't flash at all! Contacted st2 systems to which I was told to install it with the wires tilted higher than the rest of the unit which I had already done - waited and tried it in my sfv650 as it should be smoother but still the same, they don't reply to my emails now and are dire aftermarket care. They take your money and go! not happy at all!

St2 what a company A great company to order from very forthcoming with the emails when I asked about anything arrived safe and sound just waiting to be fitted and also got a free Bluetooth which sweetened the deal a big thank you very much to the st2 guys

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
