My friend with auto repair shop is on his 2nd SnapOn, it certainly comes out often. Close to 40yrs in business.
You working on that large machinery it does not surprise me that it falls apart faster.
Home wrench like me, should last minimum 3-5 years for battery job, lifetime for air unit. I just do not have a need for air compressor that can feed it the air it needs.
Majority of my power tools are cordless, convenience and no cords/airlines to mess with.
Most recent purchase was M18 tire inflator Sceep posted.
Got tired of dragging my small air compressor, air line etc just to quickly air up a tire.
