From blackhawke88's group buy
Not adequate. The lack of peanuts or other packaging material allowed the postal service abuse to Dent the ballasts and crack one of the plastic globes that protects the bulbs.
The product itself looks and feels to be of cheaper quality than my other HID kit for my headlights, (SlimCubby). The brackets are very flimsy. The ballasts are made of a very light plastic or Aluminum.
The 75 watt 6000K kit fits beautifully inside a pair of Hella 500's. The bulbs are shorter than the other kit that I have for my headlights.
Disclaimer: I am in no means bashing this product. This is intended to be an objective review of the product based on my observations and comparisons to other products that I own.
