This grease gun kit, DCGG571M1, is a joke. I bought better tools at discount flea markets for 10% of this investment and it out proforms this tool. WHY?? Where has the quality gone? Yellow is not the way to go. Service center tells me it is not worth fixing after 6 months......REALLY? No pressure to flow grease in any weather conditions cold or hot.

I recently bought one of these for the company that I work for. I have what I thought was the compairable model to this grease gun, a Milwaukee. Id would rather use a hand pump gun over this hunk of junk. The one thing this pile is good at is nothing. It leaks when it sits, its slow, it has zero power to power through a clogged zerk. I wish I would have went with my gut and spent more money on batteries and a grease gun from Milwuakee. BUYER BEWARE!!!!!!!!!!

I purchased this due to the having to grease different types of bearings and motors. I have rheumatoid arthritis and pumping grease by hand is tough when I have flair ups. It is easy to use and easy to prime. I love it and look forward to many years of use with it. It seems very powerful and even has a light that comes in handy in dark areas

Makes a dirty job much easier. Wish I had one years ago. I have other Dewalt tools and have batteries and a charger. Batteries must be bought locally in Hawaii, the prohibition has to do with shipping by air. This lube gun is so much better, that putting off lubing because it's so awkward is not longer an issue. Also recommend putting on a lock n lube long nose tip. Also a huge improvement. Love the combo. More than worth the money.
I bought this because I formerly was using a mini Lucas Oil brand manual grease gun to lubricate my John Deere 3025. Then I bought another, larger, tractor and a new tandem axel trailer and realized this was insanity. So I took the plunge and bought this tool. I already own a full set of DeWalt power tools so I opted for the tool only. This grease gun is built to the same standards that all you can expect from all other DeWalt tools. It's a hefty tool but it's got a nice shoulder strap to offset the weight. Also, the long hose allows you to reach tough spots and set the tool on the ground if need be. The light is very helpful and bright. This gun runs John Deere Polyurea grease flawlessly. My one major recommendation is to buy a Lock-and-Lube coupler as it's a ... MoreI bought this because I formerly was using a mini Lucas Oil brand manual grease gun to lubricate my John Deere 3025.

The light is very helpful and bright. This gun runs John Deere Polyurea grease flawlessly. My one major recommendation is to buy a Lock-and-Lube coupler as it's a perfect compliment to this tool. I bought the XL version, and I glad I did. Battery life has thus far proven excellent. Flow is great and each fitting is greased to spec in a few effortless seconds. Loading the gun is very simple and much easier than the mini gun I had. The empty grease tubes also come out with minimal effort. I have had no problem with purging any air from the gun---which is easily accomplished with the bleed valve. In my first day of ownership I greased two tractors, a 12-foot flexwing bushhog, and two sets of trailer axels and I could have done more. Definitely worth buying if you like being productive.
I have had this Grease Gun for at least three years and it still pumps grease faster than I can with a pump system.It will put grease in any grease fitting that you can get the grease head on.Plenty of power to drive the grease home.Not too heavy , easy to carry.CONS: No Shuttle Grease Tube System or at least a kit to retrofit an already purchased grease gun.My biggest problem is not DeWalt's fault, it is leaking grease in the barn... I bag the end now but a sealed system would be a nice add-on.Also, I now use the LockNLube Grease Head.
When faced with the daunting task of keeping my new Kubota tractor lubed, I felt overwhelmed. There are about 48 grease fittings, all thirsty for that famous blue lube. What to do? When the DeWalt 20volt grease gun came along I was immediately curious. I'd recently converted from 18 to 20 v. hammerdrills so I knew those li-ion batteries pack a punch. At the recommended 10 hour interval I parked the orange beast and commenced trigger-greasing. Wow. After well over 50 years of operating an old-style, lever action lube gun I am an instant and lifelong convert. The only caveat is to pay attention to detail and be sure to bleed all the air out of the appropriate port after loading your grease. This is so much faster with less waste! Yes, it's pricey. But to me it is ... MoreWhen faced with the daunting task of keeping my new Kubota tractor lubed, I felt overwhelmed. There are about 48 grease fittings, all thirsty for that famous blue lube.

But if you are faced with a plethora of thirsty little zerks to feed, put two C-noted down and come up to the best lubricating tool on the market today...
I recently purchased a brush hog mower that had not been greased in several years of use. It has over 30 grease fittings. My conventional hand-pump grease gun was able to push grease into only a few fittings. I decided to buy this cordless grease gun since it was rated up to 10,000 PSI. I was able to push grease into about half of the fittings. After carefully removing the remaining grease fittings, I found they were completely blocked with dried grease and rust. I replaced the rusted fittings and tried greasing again. The pump bogged down at first, and pumped grease out of the safety bypass. After a few cycles the grease began pumping through the fitting and into the dry hinge joints. This grease gun is a brute. I highly recommend it over a conventional hand-pump ... MoreI recently purchased a brush hog mower that had not been greased in several years of use. It has over 30 grease fittings.

You are reading this review because you are (1) considering a cordless grease gun and (2) comparing various brands of them. Let me save you some time and potential frustration: add this to your cart and be thrilled by how awesome it is 2 days later. Also got a lock-n-lube coupler for it which takes it from an A to an A+. Battery lasts forever, easy and clean to load, primes in seconds, makes the most stubborn zerks yield in defeat, long hose, sturdy case, includes battery and charger....nothing negative. Yeah its a couple hundred $ to do same thing as a $20 manual grease gun. But worth every penny. If all you have is a riding mower with 4 grease fittings skip it. But you have a tractor, backhoe, tandem axle trailer, etc....yeah you want this. I tried to go cheap ... MoreYou are reading this review because you are (1) considering a cordless grease gun and (2) comparing various brands of them.

But you have a tractor, backhoe, tandem axle trailer, etc....yeah you want this. I tried to go cheap route and got a different generic one and it was horrible. Battery always dead, no pressure for stubborn fittings, hard to reload...wasted $. Just do it right and get this one, be confident you made an excellent choice. And i say this NOT being a DeWalt fanboy....all my power tools are Bosch and Hitachi so i have no battery overlap with this but still think it was best choice. Hitting 30-40 grease fittings servicing a piece of equipment is a boring unproductive chore. Do it in a few minutes and with no mess with this instead :) Is it more of a luxury than necessity? Probably, but you will definitely say "why didn't I buy this years ago?"
so I ordered a new Dewalt DCGG571 20v Grease gun. When it arrived I put the box in my shop to open later. In a few days i opened only to find that it had been used. There was grease all over the hose and the housing. The grease chamber was half full of grease. I will never order anything from you guys again, I cant believe you sent me a used gun, when i ordered a new one.
