Amazing to have electric power over fighting with hand held manual method. Takes so much of the guess work out. Yes reviews are correct lack of light and the hose it too short. Priming is fast and easy. Made greasing 2 vehicles in no time while it was cold outside. Worth the upgrade. Still was questionable on the tight fit of toyota 4x4 driveshaft. Not entirely sure it went in. Might consider a lube lock head upgrade later on.

This grease gun has made the chore of greasing my tractor and implements significantly easier—it's as simple as squeezing the trigger! The unit works well, and the included DeWalt fitting performs exactly as expected. I did purchase a separate tip (not yet installed) that looks like it will be even more user-friendly, but honestly, the tool is already a huge time-saver right out of the box. Highly recommend this grease gun!

Works great. Get a quick fitting for zerk fitting or youre gonna be pulling a lot. Super quick and no hand pain from pumping.

I watched a video online on how to use my Dewalt grease gun, which made it easy to load my gun and use it. First time out, I was able to grease my tractor and excavator in less than 15 minutes. Doing this with a manual grease gun is a lot messier and slower. My first impression is that this is a great tool.

If you have a lot of greasing to do - maybe bought a tractor and 3 or 4 implements to go with it, and the tractor has a loader and a bucket or forks on the front of it so you have a LOT of zerks to grease, a gun like this makes the job a lot easier. I went with Dewalt because I have the batteries, and so far the DeWalt gun has worked great. Easy to load, easy to use, no issues.

I bought this product because I trust the name dewalt and it didn’t let me down. It works flawlessly as I expected. Now understand this unit is heavy for what it is but the hose is long enough you can sit it on the ground and still use it. So why the 4 stars. I bought and quick connect adapter to go on the end. I tried everything in my tool box to take the end off but never did succeed. I endured up buying a completely different hose so I could use the adapter. I’m not sure as to why it would not come off. It was like someone had put it on with lock-tight. .

Frankly, you can get by with a much lesser grease gun than this, and it would probably be tough to justify for anybody but a well equipped professional or a really hard core do-it-your-selfer. This thing was not cheap..... Having said that, anybody who has spent anytime under a car, truck, or RV trying to grease hard to find and access grease fittings knows the frustration of trying to keep the coupler from going crooked or popping off altogether from a difficult fitting, all while trying to pump the gun in a confined space. For me it usually results in grease leaking out everywhere and neighbors closing their windows to avoid the profanities. This gun changes all that. Some have called it a game changer, and they may not be wrong... After one particularly hot, sweaty, frustrating job where I ended up trashing 4 non-working-at-the-time, cheapy to not-so-cheapy conventional chinese grease guns and 2 air operated china guns I decided to break down and buy something decent. (I don't know...Is Mexican made automatically better?) I'm already married to the Dewalt 20v/60v stuff, so choosing a brand was pretty much a no brainer. So, in for a dime, in for a dollar.....I also bought and installed a LockNLube coupler right out of the box along with a LockNLube 90 degree coupler for use when necessary. (The LockNLube coupler simply clips firmly to the 90 adapter. Too Cool....) When using the straight coupler, if you can get the coupler on the fitting, it's not coming back off until you want it to. When using the 90, you may have to hold it in place, but that's a whole lot easier when you don't need 3 hands like you do with a pump gun. (The LockNLube is killer, and probably 50% of what makes this rig great. I personally wouldn't get one without the other.) I was always disappointed with both of my air operated, hand held grease guns. They worked well on most fittings, but it seemed like every job had at least one plugged fitting the air powered guns couldn't handle, resulting in having to go sift through my tub full of oil dripping, old conventional grease guns in hopes of finding one that works well enough to to bust through the dirt/dried grease. Not so with the Dewalt. I have yet to encounter a fitting it couldn't blast through. I read a review of someone who claimed the opposite, that their gun couldn't push grease through much of anything without the relief valve popping off. I'm pretty sure that had to be a defective unit. I have been a mechanic for about 45 years now, and this is easily the strongest gun I have ever used. Overall I can usually finish in a fraction of the time, without all the frustration. It's worth every damn penny to me.......
