I am 100% satisfied with this product. I was concerned that only one socket would be offered for the VW Jetta. In most cases the correct parts for my MKIV Jetta have to match the engine/transmission/equipment level exactly. I called the company direct and my voicemail was quickly answered by a very polite and helpful representative who reassured me that this socket would fit my vehicle. It knocked me out and my car is back on the road.
