Turn system Turn system - great, works even better than expected, 5 stars Brake module - first installation i had the brake light continously turning on. Contacted support and they gave me some tips - a bit of fine tuning and a foam pad under the device made it work great. It would be nice if this was tuned in the factory so i give it 4 stars. It does now what it should, and especially at the price they offer it i can recommend it. If it was more expensive I would not buy it. Overall 4 stars

Wonderful Modules and Customer Service I have to say ... the ST2 Systems is great. I made a wrong order and got the breaking Modul instead of the strobber. It was entirely my fault. Nevertheless, sending an email was enough to get a response that I didn't think possible. I can keep the breaking modul and they sent me the strobber for free. That's on hell of a customer service. I whole heartedly suggest you try them. Mduls work very well on my XVS 1100 Dragstar, btw :-) ... Very happy

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!

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.

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
