I have had 2 of them for about a year. They work great and are stronger than any 1/2 inch air ones I have used. I have sat on some crank bolts with other quality guns that just wouldn't do the job. This thing has broken everything we have tried it on (automotive). The only industrial type application I have tried was on a tractor blade with some large bolts 36-42 mm I don't remember exactly, the point is they all broke with no issues within a second. By hand, those nuts would not brake with a cheater bar.
