Rated 4.4 out of 5 by 13 reviewers.
Rated 2 out of 5 by Battery problems The battery will not stay charged. Couldn't even get through a half of a tube of grease. When it works I am very happy with it. Will be returning and try to get a new one. September 4, 2014
Rated 5 out of 5 by Very useful. Only one can grease excavator tracks. Very powerful. May 6, 2014
Rated 5 out of 5 by 18 volt Milwaukke grease gun Excellent grease gun. good quality, fair price. Would recommend and would buy again. June 18, 2014
Rated 5 out of 5 by A Great Grease Gun I love this grease gun. It is strong and very fast. It also has a dial that sets the amount of grease the gun will pump when the trigger is pressed. I love this feature. I set mine to number 5, which means it automatically pumps 5 times and stops. If I only need 3 pumps of grease, I can let off of the trigger after 3 pumps manually. If I need more grease, I can repress the trigger for another 5 pumps. Of course I could change the dial setting. I think the instructions said the dial goes from 1-15 or 16. It is so nice when reaching hard to reach places not to have to think about how much grease is being used. It saves so much grease. I also love the longer 4' hose. It makes greasing so much easier. This gun comes with a plastic case, so you can put it in your trunk without worry about getting grease on anything. I would not of bought it if there was not a hard case that came with. It also come with a shoulder strap. That would come in handy if you had to carry it any distance such as industrial use like greasing conveyor belts. In my case, I do not use it greasing dump trucks, tractors and equipment, but I can see it coming in handy in other applications. Since I only had it for a short time, I can not say how long it will hold up, but it has a great warranty. June 4, 2014
Rated 1 out of 5 by This product did not work at all. I received the product and was excited to finally own a battery powered grease gun. Well, not so much. This is a waist of time and a non working machine. Trust me when I tell you, use a air driven one or manual pump. Very bad investment. March 25, 2014
