I was very pleased with this socket set. The sockets are heavily made, Very well built, very sturdy, and the selection of swivel sockets are a definite plus. Note, I am not a professional mechanic. I am more of a hobbyist, and do minor maintenance on my vehicles from time to time, so I am not putting every day use, misuse, or stress on this socket set. That being said, for my use, and being impact rated, this set will more than likely last me for the rest of my natural life. I am very happy I purchased them, and definitely recommend them to anyone else like me, or a mechanic just starting out that is on a budget.
