I was a bit hesitant to buy it because it's a bit expensive but it's definitely worth it. The tools feel very good and are razor sharp. I was afraid to take on this project, but it turned out to be a lot easier than I thought. As long as you take your time and don't force anything too much, you'll be fine. It is imperative that you keep the tools straight or they will cut crookedly because they are so sharp. You also get a few extra liners in case you screw up one or need one for another car. I also used red high temp sealant on the insert although it's not required. I'm glad I only had to spend $115 on this product and about an hour of my time instead of buying a brand new oil pan!
