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.

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

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

Faulty units - absence of customer service. Unit does not work properly; tried to talk to tech support one unhelpful response. Now ten days of no responses. Referred as a dispute through PayPal. I note that they are bringing out a new unit - I would avoid it like the proverbial!

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/
