had a dewalt cordless. Heavy, and slow. Bought a Lincoln, pneumatic. Problem solved. Fast, light weight but requires compressed air to work. That is it's only downside. I use mine every single day since 2012 I think. I've got an issue with it too, hard to get it to prime and occasionally won't make much pressure, so it might be time to consider replacing it; and give this one to my brother. He don't use a grease gun much but his shop burnt down and he's starting over from scratch.
