[Closed] Grease guns-any recommendations?

I don't think there's much difference really. They'll all pump grease out. Some have long and short nozzles, some you have to fill manually while others screw onto a tube of grease (but then you're limited to the brand of grease you can use)

I've had a Dualco gun for years and it's still going strong.

The basic ones that work with a tube of grease are, well, not very good but adequate for most purposes. Can be expensive in grease but then you don't use them that often. A really good gun's a luxury, I had to give "my" brittool one back to my uncle, it was a lovely bit of kit.

don't stick it in your ear
