Like most people, I was skeptical prior to purchasing this item. I did my homework and checked around reading other's reviews. Once I installed it on my car, it was noticably better.

Honestly was very pleasently surprised. Truely slim ballast, installation was a breath, for exception of lightbulb housing, but that was car specific and has nothing to do with the product. I definetly see the difference vs. stock, very happy with the result.
I'm pretty sure this is a generic, but for the price I was very surprised to see quality. Had it for about a month, works like a charm.
