High quality do not have to worry about breaking and if the product does break i can return for another, Comes in a nice case to keep all sockets and socket wrench together so you don't loose any. I own several craftsman tools and different wrench and socket set and love them all. You can not go wrong with this set. I have used these sockets a lot working on cars. I have never had problem with them. I have used other brands that do not hold up up pressure. Craftsman stands behind there products so you know you are not just throwing your money away. Socket wrench and sockets connect easily and keep a good connection. They are made of a heavy metal product and do not break easily. They have a lifetime warranty and come a range of sizes to handle most metric bolts. Since it comes in a organized carry along box it is easy to take with you . I would recommend this product and any other craftsman tools.
