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

Impressive customer services ST2 customers services were quick to respond, totally understanding of my situation and were equally quick to reimburse me for a product that was gifted to me as a duplicate. Thanks to Philippe for a clear and helpful correspondence in resolving this matter.

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.

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!

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
