I'd argue then that the level of usage dictated a better one. Most people don't actually use tools to failure. I've owned edging tools, routers, sanders, even a small metal lathe from Harbor freight that have handled 10+ years of very occasional use just fine. If you're using things so much that they fail, yes, buy a more quality version. If it fails on the first use, Harbor freight happens to have a very generous return / exchange policy within the first 30 days.
