I have used it minimally so far, but it works without any problems. Pay attention to the torque - it is not advisable to use a powerful air wrench/electric wrench with a 1/2" drive and apply all its power to a 5/16" bolt.

It worked well for a long time. When I pushed it too hard with a very strong impact, it broke at the neck (I expected the tip to break first, but it was of very good quality and the adapter broke instead). However, it does what it promises, and if you don't push it more than necessary, you won't have any problems.
