Dire customer service and rubbish product Installed on an aprillia RS4, constantly flashing unless unit is near vertical in which case it doesn't flash at all! Contacted st2 systems to which I was told to install it with the wires tilted higher than the rest of the unit which I had already done - waited and tried it in my sfv650 as it should be smoother but still the same, they don't reply to my emails now and are dire aftermarket care. They take your money and go! not happy at all!

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.

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.

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.

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
