I've always had Craftsman cordless tools but in searching for a cordless grease gun I decided to switch to Dewalt. Ordered a combo kit with the 20v grease gun, 1/2" impact wrench, and worklight. Got the Lock n Lube also. Looking forward to the grease gun. I've used the typical manual gun for many years, tried a cheap Central Pneumatic air gun, which was more of a PITA than what its worth. From what I see here the Dewalt should be the ticket. I have 32 fittings from the FEL to backhoe, several on the dump trailer, atv's, etc. It should get a workout now and then. I'm anxious to try out the 1/2" impact on lug nuts too.
