I used the regular bulbs that came with the headlights for a good month. I was very satisfied with them. Then I went and purchased an HID kit that made me love these even more.

Aligning them is kind of a pain because you have to do it from the back of the projector part which means you have to take the headlight off of the car to adjust them and then put them back on and then off to adjust them. Not too bad if you know what needs to be adjusted.
