I am a professional Master Mechanic. My tool chest is full of SnapOn, Matco, and Craftsman. I do have some Harbor Freight tools in there too. I purchase HF tools when there is a unique tool that I will rarely use. They have unique automotive tools at easily 1/3 the price or less of SnapOn. My only advice is to choose your tool carefully, and decide how much you intend to use it. Sparingly is OK, but if you are a serious technician, I would go with a higher grade. How much is it worth to you if you purchased a HF 1/2" breaker bar and in trying to remove a bolt, the breaker bar broke sending you to the hospital. Evaluate each product. My home battery charger, air compressor, and much more are all Harbor Freight. It does not need to be any better than that for my occasional home mechanical work.
