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

What a load of rubbish!! What a load of rubbish!!! Fitted to my 2016 triumph street triple and all is does is flash under acceleration and deceleration. Appsolultly useless do not buy from these people I messaged them multiple times and only got one reply asking if it was fitted properly. The answer is yes it is as I am a 25+ years mechanic. This is junk item….

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!

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

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.
