Finally, a wonder product that does what it says! I've been struggling to grease my beam properly for a while and the vast majority ends up in a pooey pile on the Tarmac. I'd even tried one of those oil injector nipple unblocker thing that mostly created a piszy pile on the Tarmac. But with this jobby screwed to my trusty old gun the grease goes straight in, no messing! Highly recommended to those with a similar beam affliction.
Yep, definitely muppets, but pretty much a fair portrayal of muggins here after an hour struggling with my old grease gun!
