I have seen many different brands on the market and they all claim the same thing, Do they really work? And if so, which one kit is the best in your opinion.

I think they are all really about the same. If you know a great deal about cars then avoid kits. Still if you do not know as much you may want one. It is a lot like cooking. If you can bake make a cake from scratch if you cant get a mix.
