I purchased this set for a few reason Price, quality and practicality, I needed a set to save my regular set of craftman sockets from an untimely doom if i continued to use them with my impact tools and i'm glad i did they will and already have seen a lot of usage, thank you sear's for qualilty products.
I just needed a small basic set of common lug nut deep sockets and these fill the bill. I was pleasantly surprised to discover that they were made in Taiwan (the Republic of China, not the PRC). The finish is a little rougher than more expensive sockets, but you do get a good grip. As other buyers have mentioned, I don't quite see why they give you both a 3/4 inch and a 19mm. At least you will have the exact fit whether you have SAE or Metric lug nuts.
Sockets do what they should, I got my lug nuts off with no problems.
all the lugnut sizes you need
