First--the standard disclaimer that I have no financial interest in this gadget or any interest whatsoever with anyone even remotely connected to it. This endorsement is from first-hand experience with trying to use a grease gun without the device (usually a disaster) and then using the gun with this device (worked perfect--yea!).

The gadget is the LockNLube. It screws on to the end of the grease gun (replacing the standard fitting). Four "fingers" extend out and grab the zerk fitting and they hold on while pumping in grease. I actually enjoyed greasing my Blue Ox and lawn tractor last night! Today I'm going to pick up some Mobil1 grease and tackle the suspension on my trailer.

Worth every penny, if you are grease gun-challenged like me.
