Review on Slippery Pete Cartridges Flexible Extension by Mike Rajput

Sorry but I can't agree with the mostly good reviews on this grease gun. Mine has two HUGE flaws: 1 - The lid screw threads are so thin it just doesn't hold the lid. I know it sounds weird but I can screw it in until about 1/4" of the threads are showing and then it won't let me move any further and it will come loose. I think I pulled the top right once. , but after that, #2 - the piston stop that holds it when fully extended slips, allowing the (spring loaded) piston to enter the lube tube, if you don't install the top correctly and quickly you will use a whole tube of lube pop out (and waste) (which I did).No.
