To really be useful for automotive work, this needs a few more sizes (such as 12x1.5). The design also prevents you from going as deep as you want in many cases.

Initially I gave this product a good review, but after 2 uses I found that the threads were ruined on a normal non-damaged threads (Freightliner Cascadia NOX sensor) I think this product would be good for a one time use to get you out a pinch or just to have for that day. But for everyday professional use I’d recommend a much higher quality brand. Sometimes you can go cheap on tools but for this one I’d recommend a big brand if they make it (Snap-On, Matco, etc.)
