i have found that with chinese tools its sorta one of those go with your gut feeling things, weather its harbor freight or homier etc. i have a set of impact sockets from homier that are as nice as most any usa brand, and have held up well to alot of severe use, you couldnt tell there chinese if they wernt stamped, last time they came to town a friend of mine bought the same set, same price same part number, they are junk, dont fit nuts well, look like they were finished to size with a belt sander and he already has split one trying to take some bolts outa the cutting edge on his dozer. i realy think that with chinese tools ya gota look them over each one, thats why i dont like mail ordering chinese stuff, ya never know what ya will get
