Didn't work for me- got an inoperative sample.

Thought I'd pay extra to get a nice grease gun, but got a faulty unit that would not prime no matter how much I coaxed it along. Pushed and pulled the follower, hit the bleed vent until grease spewed forth from it, but pump as I may, not even a dribble of grease came out, without the hose connected, even. I tried packing the head full of grease manually to make sure there were no pockets of air, and made sure the spring was pushing on the grease in the tube, but still nothing at all. Tediously cleaned out the grease and sent it back where it came.
