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.

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.

SACMMER No shipping info Paid with discover card, I am submitting fraud alert. Three emails sent: automated responses only (today's date: 2/2/24) about being gone for Christmas holiday. Phone number is a dud and when attempting to follow website directions to use WhatsApp the phone number has no link to a WhatsApp profile.

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!
