Rated 5.0 out of 5.0 by excellent product very pleased with this purchase, the grease gun performed great December 22, 2015
Rated 5.0 out of 5.0 by Great product, very happy with performance This was a replacement for an existing unit that was damaged beyond repair. This was an overwhelming request to replace with the same Milwaukee performance and value. December 15, 2015
Rated 5.0 out of 5.0 by Don’t operate heavy equipment without it. Works as good as depicted in the video. Normal grease gun requires three hands to operate and they are to cheap to function properly.This grease gun can be operated with two hands and the quality is excellent. September 22, 2015
Rated 5.0 out of 5.0 by Works great! Saves time and energy. Great for hard to reach areas when hand pump is difficult September 8, 2015
Rated 5.0 out of 5.0 by best grease gun you can have this grease gun makes greasing your equipment so easy. the low speed works great when you need a lot of pressure [10000 psi] and the high speed lower pressure [8000 psi] for fast high volume greasing. with the pump counter you set the number of pumps you want hold the trigger down and it will stop at the preset number of pumps. the 4 ft hose makes getting to those hard to reach fittings easy. the battery will last for 8-10 tubes of grease, I have 2 of these grease guns and I do a lot of greasing equipment. the other brands don't even come close to the Milwaukee grease guns. if you need a heavy duty grease gun this is a must have.

Rated 4.0 out of 5.0 by Handy unit The built in like is great for working under my Peter built and inside combines. April 16, 2015
Rated 5.0 out of 5.0 by This product is efficient! I purchased this product to replace a manual grease gun and this product has been great! It works great, no mess and it's not very loud. The only thing I can complain about is that for the price I paid, they should at least throw in a nice bag or case for it. April 1, 2014
Rated 4.0 out of 5.0 by It works well, does the job nicely. It works nicely, I like the 4ft hose and the light features. The non-pressurized grease dispenser button is a nice touch. I wish they made them for the M28 battery as that is my standard and I had to get a 18 volt just for this tool. July 21, 2015
