It's been a while, and so far, so good...
I got this one:

It's survived, and even after a whole week of frigid temps, and me not turning the car on for 2-3 days.... still cranked up, no issues.
My car is parked outdoors, where it endures all of the crazy elements, and this little thing still pops, HID's run, all bulbs power on, no flickering....
Just an FYI
Geeks get it done, while Nerds whimper and call for mommie.
