Well at $60.31 including shipping, even if I do have to use the lifetime warranty it still sounds great! I just ordered the 55w 8000k.
At carhidkits.com It was a 1 year warranty, i had to pay shipping both ways, and it took weeks. And in the year and two weeks since I got them, I've had one defective bulb and FIVE defective ballasts from them. And the last ballast they sent me was digital, and it washes out more color than the regular one on the other side so they're completely different colors.. So as long as the product is decent from DDM I'll be ecstatic!
