Rated 5.0 out of 5.0 by awsomenessperfection i love milwaukee tools like i love my wife a lot just one shelf thats 20 inch by 20 inch on my service truck holds over 2000 $ in m18 and m12 tools i have 3 shelves i deserve a win on something lol February 11, 2015
Rated 5.0 out of 5.0 by Good Features Really like the dual settings, hplv or lphv, also you can regulate the number of pumps per trigger pull(1-50) or just pump on trigger pull. It also has a handy LED light. Easy to use. I added the lock on attachment from Amazon(Lock-n-Lube). January 1, 2015
Rated 5.0 out of 5.0 by Grease Heaven I've used it a couple of times now and it works great. No more trying to reach for fitting while pumping by hand. Plenty of reach for my needs on a garden tractor and JD tractor. I love how you can hold the trigger down for continuous feed. Seems well built. I wasn't going to buy this due to the price, but I had just bought the brushless M18 combo package and like them so much I went ahead got it as it was cheaper just for the tool without a battery September 24, 2014
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 5.0 out of 5.0 by Best grease gun I have ever tried I have had many different kinds of grease guns, electric, air, and manual, this out performs them all! We sometimes use up to 6 or more tubes of grease a day and that doesn't even phase this gun. I will be buying more. April 24, 2014
