"I'm not usually a DeWalt fan, but I have to admit, this grease gun is a game-changer for heavy equipment maintenance. The battery lasts a long time, it's easy to use, and I can get through dozens of fittings in minutes. After struggling with a generic model before, I wish I'd just bought this one sooner—it’s worth every penny."

"The cordless design and long hose make this tool extremely handy for reaching tricky spots. I love that it comes with a battery and charger, and the variable speed trigger lets me control grease flow precisely. This is a high-performance, reliable grease gun that makes the job much easier."

"I use this grease gun for my class 8 tractor, and it has eliminated the hassle of manual pumping. Although I wish the hose was a bit longer, it's almost a pleasure to do lube services now, and there's no more leaking oil on hot days."

"Honestly, this is the best power grease gun I've ever used. The hose is plenty long, and the pressure is perfect for even tough jobs like worn kingpins. The powered trigger makes it so much easier, especially when you don’t have enough hands for awkward angles. I do wish the case was easier to clean, but overall, this tool is hard to beat for general use."

"After switching from a manual gun, I’m amazed at how much time and effort this grease gun saves me. I have a lot of farm equipment, and now it takes just a few minutes per machine. The pressure is fantastic, and it’s simple to load and operate. If you want to avoid headaches and make greasing painless, this is the tool you need."

"I’ve added the Milwaukee 2446-20 to my toolkit and it’s been a game changer for vehicle maintenance. It’s compact, easy to handle, and keeps my work efficient and tidy. Since I already use the M12 system, it fit right in. I’d definitely recommend it to anyone looking to speed up their routine."

"Switching to this electric grease gun has made greasing my tractor and implements incredibly simple—just a squeeze of the trigger and I'm done. The included DeWalt fitting works perfectly. I bought a different tip for even easier use, but honestly, this tool is a huge time-saver from the start. I highly recommend it."

"I bought this because I trust DeWalt, and it didn’t disappoint—works flawlessly. While it’s a bit heavy, the hose is long enough to set it on the ground while working. The only hiccup was trying to replace the end with a quick connect adapter, which was tough to remove, but overall, I’m happy with the purchase."

"After watching a quick video, I was able to load and use my DeWalt grease gun easily. Greasing my tractor and excavator took less than 15 minutes—much faster and cleaner than using a manual gun. My first impression: excellent tool for the job."

"This grease gun is a real time saver on my farm—I wish I’d had it years ago! It’s made daily maintenance so much quicker and easier."

"As someone who manages a maintenance department, I can say these are excellent grease guns for daily use. Reliable and effective, I’m already planning to order more in the future!"

"I've been using manual grease guns for years, and switching to this electric grease gun is a game-changer. The 12,000 PSI power makes greasing fittings effortless, and the dual batteries last a long time and recharge quickly. The 90° swivel coupler is perfect for reaching tight spots, and everything feels sturdy and well made. Maintenance on my truck and equipment is so much easier now. Highly recommended for anyone who works with machinery."

"This electric grease gun completely exceeded my expectations. It has excellent power and the 2-in-1 design is super convenient for using either bulk grease or cartridges. The batteries are strong and the fast charger keeps me working without interruptions. I also appreciate the swivel coupler for small spaces and the overall high-quality build. It comes with a full set of accessories, making it ideal for both professional and home use."

"As someone who works on heavy equipment, I rely on this grease gun for its strong pressure and long hose, which really help me reach those tough spots. The LED light is a lifesaver in low-light situations. My only complaint is the port opening—it can be a little awkward during use, but overall, it’s a solid tool."

"I’m still getting the hang of using it, but I love how securely it latches onto zerks and how quickly it pumps grease. The fact that it comes with two batteries and a charger is a huge bonus for me, especially since I already use Makita tools and can swap batteries."

"My factory tube collapsed, making it a pain to reload, but this replacement is far better engineered and made the whole process much smoother."

"While this barrel worked for my Ryobi, the plunger spring was very stiff, which made loading a bit tough, but I'd still take that over a weak plunger any day."
