I use the wrench exclusively in the DIY sector. The quality convinced me they are well in hand, are not too heavy and comfortable grip. Processing appears - as far as I can tell - very good. Which loads the ratchet endures, I can not say. For fixed screws I would rather first with the other side to try to solve the screw and then fix with the ratchet. Even when tightening a screw, it is - probably in general - makes sense, completely tighten the screw at the end without ratchet function.
All in all I am very satisfied and definitely appreciate the new comfort :-)
