Very Greasy. Works great on rails and lead screws. I'm tempted to try it on a squeaky wheel, because I have more than I needed for the Trident!
I like the removable needle for greasing rails via the "add a bunch of grease through the back side via one of the mounting holes" method, and it's good for greasing up lead screws. The needle is nice to top up the grease ports on the rail carriages for the House brand rails that were pre-greased.
