Review on FIXSMITH Cartridge Professional Reinforced Extension by Shigg Bigbee

This is my first grease gun and my first time using it. After watching numerous YouTube videos when I received mine I was able to put everything back together. I bought a 14 ounce WD-40 all-purpose lube for this and it fits perfectly. Replaced all wheels on my lawn mower and lubricated the gearbox and axles. When I first put the grease tube in the gun, the pumping didn't work. I unscrewed the threads a full turn or two to let air out when I let go of the piston. It didn't work a couple of times so I decided to remove the bleed valve with a hex screw. Dude he was shooting all over the place when I heard "pfft" lol and it wasn't me I assure you. I hurried to put the bolt back in place, wiping off all the grease that was on it. I love this little grease gun! I hope this is the only one I will buy in my life.
