Cordless grease guns. Worth it?

I have over a dozen good grease guns. (And a few junkers for parts). I have never had a cordless grease gun. Early ones neighbors had they overgreased stuff. IMO more harm then good. Most stuff I give 3 pumps at start. Maybe 3 pumps just before dark if running long.
Neighbor says it’s very handy for zeros that freely move. Single disk blades. Where it’s hard to hold hose on movable fitting, find object to force gun against as you pump. I can pick a new one for $225 with battery, charger. (Plenty batteries/chargers right now). So maybe the Amazon bare gun $163 shipped?
CPO gun with 5ah battery, no charger $180? (But no bag, carrying case)
I go thru 8 tubes a year now. Since I stopped combining my corn/beans. Those that have it. Is it worth $200?


Neighbor forgot it on combine wheel. Very painful. If I forget a grease gun, no damage to machine. It’s $20 max
