The company offers no support The company offers no support, after trolling you for your email address by offering to send you via email the results of your comparability test to see if their product will fit your motorcycle. Once they get your email, you are spammed relentlessly daily regarding “10 more discount codes left” “50% off”, even after you buy, and you can bet they are selling your info. The phone number on their website rings and answers to a dead line. When I emailed Support, I was given a generic email that basically says you are on your own! Documented my install on my Yamaha YZF-R1M of this crap product and company. Countless hours trying to figure this out, with no help from crap-systems.com. Here is my install www.r1-forum(dot)com /threads/st2-systems-com-brake-and-turn-signal-modules-warning-this-product-sucks.645340/

Don,t use this company, complete waste of space 1st brake light switch didn't work, they sent a 2nd and this didn,t work either so returned the item costing me £12, then this was returned by Slovinia customs ? been trying to get through to these people since last June, they promise a full refund , the company,s a complete joke, steer clear !

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.

What a load of rubbish!! What a load of rubbish!!! Fitted to my 2016 triumph street triple and all is does is flash under acceleration and deceleration. Appsolultly useless do not buy from these people I messaged them multiple times and only got one reply asking if it was fitted properly. The answer is yes it is as I am a 25+ years mechanic. This is junk item….

Brake unit too sensitive! I ordered this from NZ, took about 3 weeks to arrive, no problems there. Fitted correctly, but I've found the sensor is much too sensitive. Brake light flashing almost continuously even though I've installed with the wires very high as instructed. I've had drivers pull up at he lights to tell me my brake lights flickering almost non-stop! I've disconnected as more dangerous than not having it.
