I have a DeWalt electric grease gun and it has been great. I'm not sure why some guys make a big deal about whether a gun is manual or electric. I can pump just as slowly with the electric as I can with the manual. The electric is nicer for quickly running through a machine with a lot of zerks. One hand connects the line to the fitting, the other hits the trigger. Pop it off, move to the next and do it again. No hand repositioning. With a manual gun you have to remove that hand from the fitting and use two hands to pump. On a machine with 30+ fittings that can add a bit of time and even more mess.
