i finally got mine installed today, after the month or so of waiting for manufacturing and shipping. build quality and precision is second-to-none. installation took less than 5 minutes for both sides without even looking at instructions (it's that easy). they look awesome and i'm completely satisfied. pictures on here really don't do them justice...they are much more vibrant in real life. i can't wait to see them at night! they already look 100x better than my previous GP thunders in the day, especially in the reflection off black cars in front of me.
