Over the last ten years I've used this tool to pull maybe 2000 1/8" diameter blind rivets up to 3/4" long in soft aluminum aircraft engine cooling baffles.  It is tiring on jobs that require more than a few dozen at a time, but the swivel head makes up for that in awkward, hard to reach places where major diss-assembly is the only other option.  For repetitious or heavy-duty work with easy access or Cherry-Max and Riv-nuts we use hydraulic and straight-pull manual pullers.  That said:  A rivet tail occasionally sticks in the tool and needs to be fished out:  A drop of 3-in-one or other light oil works wonders. There is a nut in the handle that needs occasional adjustment or a self-locking nut or Lock-tite.
