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!

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.

Customer service not existing I ordered the brake-modul as the concept seems interesting. ST2 confirmed the compability with my bike but when I received the unit, it did not fit at all. Seems that they changed the measurements on the module. I was not too keen on the location they recommended (on top of the rear brake reservoir) but I thought I give it a try. There is no way however that unit does fit there. I tried to contact them, to use their return/money-back guarantee but they just ghosted any attempt. Funny enough they reach out to me all the time with new offers, but no response on email, facebook messanger, what'sup etc.

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.
