I am a Rv Service provider as
I am a Rv Service provider as well as a former ASE certified technician. I have always had a mix of snap on, Mac and matco tools with a variety of Harbor freight tools in the mix. It's not as much as the tool being used but rather the abuse you give a particular tool. I have never had problems with HF tools. They work as intended as far as I have noticed. So say all the tool slamming you want too. My tools are as good as the knowledge I bring to the repair center.
