Greasing my tractor always presents challenges - having only two hands is one, difficult to access zerks is another, and making a mess is yet another. I used the lock n lube for the first time yesterday and love it. I hesitated getting it because of the price, but I see that it is going to be worth every penny in the time I will save and the messes I will avoid. I likely spent as much on other grease gun accessories in the past few years trying to find the best way to get er done - and have broken some zerks in the process. I am a very satisfied user.
