Files are somthing I wouldnt skimp on. You want files made out of a good high carbon steel. If you're just using these around the house, you'll be just fine. These will last you years. But in a shop atmosphere, these things probably wouldn't last a week. This is the standard set my work gets us and it lasts about 3 months until you need a new set. All in all, I think you got a good deal. Just make sure they dont touch eachother, because a file will damage another file.
