I have always had great service from Peter at Alradco. I purchased a radiator a couple years ago and it was a very smooth transaction and a great product. I purchased low beam HIDs over a year ago and recently purchased Hi-beam HID lights from Peter. When I received a bad ballast on the Hi-Beams, Peter immediately responded to my correspondence and is sending out a matching pair of new ballasts to replace one bad one. Thank you Peter for your customer service!
