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.

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 !

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!

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

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/
