I purchased this kit for an automotive repair job and it was a complete disaster. Thanks to my knowledge gained in practice, I was able to see that the kit's design was poorly made, and the parts were of low quality. The instructions were confusing, and I had to spend several hours trying to fix my mistake. The only positive thing about this kit is that it came with a few extra parts, but they were all useless in the end. Save your money and purchase a better quality kit.
