I have purchased several products and… I have purchased several products and have had a great experience with the products and service. First was the turn signal module for my KLR 650, which I needed, I would ride for miles before turning them off. Thank goodness it works as it should. Recently I ordered to brake modules. One for my Harley Road king and one for our (Hers) Cam Am F3L Just installed a couple of days and appears to work as stated. Haven't had it out on the road yet. OK, so here is why the best customer service I have had anywhere. I received two Flasher modules instead of the Brake Modules. I emailed about the situation and had a response next day only to find my order was for the flasher modules. My bad. Customer service has sent me a brake module for free! Waiting for delivery now.

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

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

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

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.
