Need advice on a grease gun that will actually work. The last few I bought were better as paper weights. Most of them only managed a few squirts of grease for each new tube of grease. And some, the actual act of inserting a new tube of grease in them was well.... Like trying to hold and eat a soup sandwich. What brands/models do you recommend. Not looking for anything high end just need one to lube the utility trailer and a few parts on the car every now and then. Smaller would be better.
