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!

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

SACMMER No shipping info Paid with discover card, I am submitting fraud alert. Three emails sent: automated responses only (today's date: 2/2/24) about being gone for Christmas holiday. Phone number is a dud and when attempting to follow website directions to use WhatsApp the phone number has no link to a WhatsApp profile.

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.

Impressive customer services ST2 customers services were quick to respond, totally understanding of my situation and were equally quick to reimburse me for a product that was gifted to me as a duplicate. Thanks to Philippe for a clear and helpful correspondence in resolving this matter.
