[This review was collected as part of a promotion.] If you do any meaningful work on your cars, sooner or later you will need deep sockets. With a fleet of older cars, for me this is a must have. I have already used it for replacing the starter on one car will be using shortly to replace a leaking clutch master cylinder on another. The sockets are well made and feel like they will last a lifetime.The magnetic rail is a nice touch. I also like that these are 6-point socket and prefer them to 12-pointers, especially in larger sizes. The only minor complaint is that I wish the set also included a 10mm, even if Craftsman had to drop another size (is anyone using the 23mm?) from this set. Just like most sets, there will be some sockets that will never get used but it still makes more sense and costs less than piecing together individual sockets you need.
