Bunch of guys here HATE DDM with a passion and have many stories just like the one above, and many worse. I've never bought DDM but I think steering clear of them is most likely a prudent choice. Have you tried just replacing your bulbs with silver stars? HID's aren't really much if any brighter, and when they do fail you're talking uber bucks to replace them (not sure the cost out weighs the gain). Plus you're going from 12 volts up front to in some cases 12,000+ volts (thanks to the high voltage ballasts true HID's require). It'll spank you GOOD if you don't know EXACTLY what you're doing.
