Rated 4.6 out of 5 by 8reviewers.
Rated 5 out of 5 by Use the grease gun to grease equipment. Works great and saves time. The 12 volt batteries are easy to maintain and hold a charge very well. Would recommend to anyone who needs an automatic grease gun. Being a Milwaukee product the quality is great. November 18, 2013
Rated 5 out of 5 by Works everyday flawlessly in our service truck. Great battery life. June 25, 2013
Rated 5 out of 5 by Awesome gun perfect shape I am a heavy duty mechanic, in a big shop. I use it every day and I lend it out to other mechanics every day. This thing works great. The batterie life is awesome. The design of it is really nice. Best one I have ever used for an all around greaser. March 27, 2013
Rated 5 out of 5 by This is a fantastic piece of equipment. Used everyday servicing pumps and motors. Wish it came with 2 batteries. Just put it in a five gallon bucket with rags and fittings. March 15, 2013
Rated 5 out of 5 by Best one i ever bought Lots of power to blast out those hard to grease stubborn fittings November 26, 2012
Rated 5 out of 5 by Best on the market We have three brands of cordless grease guns on our farm, and everyone always goes for this one. Hands down better than the Alemite, and Lincoln guns. Battery life is unbelievable, power is great, and pump speed is perfect. November 23, 2012
Rated 2 out of 5 by Just Purchased a M12 I bought this on the salesman's advice and as soon as I got home I put it on the charger. Then tried to load up a cartridge. Had to bleed and pump the plunger, but got it going eventually. Went out to the front end loader and the zerk connector wouldn't click on to hold the hose. Tried every nipple in sight. No luck. I didn't want to ruin the connector by fiddling with it, so it is going back to the store for refund with a full cartridge of grease for the next guy. October 20, 2012
