As I read 11 pages of talk about electric and cordless grease guns, and pistol grip versus traditional two-hander with a hose, all I could think about is how little of the time I spend on the job of greasing anything is actually spent pumping grease. Getting under the equipment and cleaning the grime off the zerks and connecting to them easily takes me more time, than actually squeezing the lever on the grease gun.
So, throw me in the camp of guys who just don't understand the appeal or need for an electric grease gun, although I'll admit I don't have any equipment that needs daily greasing. My mower spindles and front trunion get greased twice per year (50 hours), everything else is once per year (100 hours).
