Automatic brake light. Automatic brake light. I had no issues with buying and delivery of the unit. After delivery I regretted my purchase as the design didn't live up to my expectations, and contacted customer support. After a while i got a response with a return address. I payed around 30 euros for return shipping, and shortly after the shipping company send me a email that the address doesn't exist. I have tried calling the official phone number, and left message on the support, but no 4 days later there is still no response from customer support.

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

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/

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

Turn System is a great add Turn System is a great add, solid 5 stars. Brake module works great on my CBR 600 but does not work very reliably on my GS1200, they refunded me for the one on the GS. My friend also has one on his Z1000 and it works great, I've been riding behind him to help him test. Overall very good, but customer service is a bit slow to respond.
