Review on Workforce Grease Cartridges Flexible Extension by Louis Asok

This is my first grease gun and I took a bit of learning although I watched the loading and use videos. Ultimately, the gun works fine once I figure out how to load it properly. On the first cartridge I just pierced the top foil seal and made a small hole. Well, it turns out that the entire gasket was pressed into the top of the gun, which kept the grease from escaping. After finding and removing it, the gun worked as it should. While relatively simple, I would like it to come with instructions or at least an assembly diagram of the parts. If you had the assembly instructions with you, you could have earned another star. I would also like the plunger to hold up better when pulling. It "unlocks" and slides forward very easily. A little push while loading before unscrewing the top and you have a full tube of lube on the bottom.
