I have a kit purchased with them. I ended up with a faulty ballast, but its being taken care of right now. The vendor is usually very quick to respond to emails and is replacing mine under warranty, minus shipping and handling costs. I love my kit, I bought a 5300K kit, and the light is pure white. No blue, and it is a little purplish when it is warming up. Uploaded a pic. There is a hot spot in the very middle as you can see, but overall the beam pattern is fantastic. I've seen much much worse. As long as you aim your headlights down the glare towards other drivers won't be bad.
