The first kit I bought from them failed after 4 months. To their credit they did send me replacement bulbs and ballasts before I figured out it was the relay. They then sent a new relay that lasted 11 months. When I contacted them for a new relay...total silence. No response to multiple e-mails or voice mails. If you call "sales" you will hear the same voice as "technical support". This is some guy in a garage. My only regret is that I did not check them out here first.
