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

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

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!
