Are these plasmablue HID anygood?

I saw this website www.plasmalights.com for plasmablue HID lights, and they say they wont mess up the stock wiring harness, and they say they have a lifetime guarantee. I e-mailed them and they confirmed that i dont need to upgrade the wiring. Is this for real? are these any good, or is the light not as bright as the 100/110 W ones that need the wiring upgrade.
