    Works very well picks up grease from new cartridges without trouble , hose is a good length just a very good greaser

    I added this to my collection of Milwaukee M18 tools a couple of years ago. Definitely, a well designed and built quality tool. Haven’t touched the manual grease guns since trying the Milwaukee. It takes a lot of the unpleasant work out of greasing machines. If you don’t have one, you don’t know what you are missing.

    I love Milwaukee tools, the grease gun just as everything else.

    Been operating heavy equipment for 20 years. The lincoln hand pump grease gun is the first manual greasers. But when I bought my Milwaukee i’d made a 20 minute job into a 4-5 minute job. and i still get paid my 30 minutes. 10 000 psi had no problem getting the clogged and stuck nibbles freed without haven’t to change or pull out the nibble and clean it. It was cheap but worth every penny. My machine never misses a grease. Only thing i’m missing is the carry case. Thanks Milwaukee. Worth every penny

    I’ve been a heavy equipment operator for 28 years As for maintaining machinery I’ve used various types of grease guns in my time starting off with the hand pump And after doing 70 to 80 Grease Nipples Your arms look like Popeyes. So needless to say when the cordless grease guns came, it was a blessing. When I purchased the Milwaukee grease gun comparing it to some other top-of-the-line grease applicators it’s definitely a Precision tool. I like the setting that delivers only the amount of grease you will need per application (pumps) and stops automatically when It has reached its setting so you are not overfilling your joints. The LED light also helps in low light situations. Also there are two positions of psi hi/low for those stubborn grease nipples. I bought the kit with the two batteries and charger also the case is nice for storing. I found the two batteries 18volts will gives you more then enough for any job or two. Great product highly recommended
