I do own a variety of harbor freight tools, but not many. The ones I do own I have bought mostly because I have a one-off need, and it is cheaper than purchasing a name-brand expensive tool. I buy it with no expectation beyond that it work for the specific project. If it fails for the project I return it to get my money back. If it works I keep it "just in case" I ever need it again. If I know I am going to use the product repeatedly I look for professional and commercial quality. The precision and longevity of such tools make work so much more enjoyable (I.e. less stressful). One example of the one off was when I built my barn/garage/shop. I purchased a framing nailer on sale for $79. I toyed with purchasing a commercial name brand product but new that this was a once off need for the tool. The tool is junk and frustrating to use, but it got the job done and saved me a few hundred dollars. Based on the quality I have experienced to date, I would not risk a professional livelihood on their stuff.
