I forgot to mention, my kits do have a full lifetime warranty. Also, no other kit comes with the harnesses that I hand assemble. Period. Some on this forum will say, "so what? Just some electrical tape is all you need..." Blah, blah, blah. Whatever floats your boat. On my car, I wouldn't do it without a harness if one was possible.
Buzzy: I can, but it opens a whole can of worms if something breaks and it's also not in my best interest for someone to piece meal a kit together. Let's just say that if I were to sell the harnesses separately, the cost of them + the cost of the cheaper kit would be what you'd pay if you bought the kit from me in the first place. Sorry.
As for customer service, I don't have tons of inventory (mostly because of said cheap kits flooding the market) to turn things around as fast as I wish, but I try to do the best possible. There was even a member on this forum who lives somewhat nearby. He said one of the ballasts went bad and asked if he could swing by to pick up a replacement. He came by and got the ballast and then called me in a few hours to say that it wasn't the ballast. So he drove his car over this time and I did the replacement myself. Free of charge. Admittedly, it's not cost effective to even do an install let alone a replacement for free if you consider the time involved and my normal professional billing rate with my regular occupation, but I do it for fun.
