This tool is not suitable for industrial and scientific use. Through trial and error, I found that it did not have the ability to continuously hold up to heavy-duty tasks .The pros are that it is lightweight to carry around. However, the cons outweigh the benefits, and I would not recommend this tool for industrial use..
Pros
Simple and reliable tool for tightening or loosening Briggs Stratton engine spark plugs.
Cons
Limited to use only with Briggs Stratton engines, not compatible with other engine models.
