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!

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

Horrible Device The device constantly activates just from the vibrations of the bike. Does NOT work as designed and is more of a danger than any kind of assistance.
