1st brake module failed 1st brake module failed, replacement was larger than original and wouldn't fit. Returned module in June 2023 and despite 20+ emails, have not received promised refund.

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!

Automatic brake light. Automatic brake light. I had no issues with buying and delivery of the unit. After delivery I regretted my purchase as the design didn't live up to my expectations, and contacted customer support. After a while i got a response with a return address. I payed around 30 euros for return shipping, and shortly after the shipping company send me a email that the address doesn't exist. I have tried calling the official phone number, and left message on the support, but no 4 days later there is still no response from customer support.

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.

SERIOUSLY PUTS YOUR LIFE AT RISK - COWBOYS! Does not work! Advertised as a lifesaving product but as it flashes all the time when not braking it's actually a life-threatening product. Was told to return it to get a refund. After sending it to the address I was told, after weeks it was returned back to me in Australia marked as rejected by Slovenia customs due to ST2 not providing some detail to their customs department. Battling with PayPal now to get a refund. AVOID LIKE THE PLAGUE!
