    • Ease of use
Style: Grease Gun Only
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. ... show more

    • If you are a hair trigger tempered jerk like me, you probably need to have one
Style: Grease Gun Only
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....... ... show more

    • Worth paying for Dewalt quality
Style: Grease Gun Only
I wish I had bought this years ago. My tractor has a lot of grease fittings, this works great. So much easier than pumping the manual gun. The hose is just the right length. Even Zerk fittings that have dried grease, this gun has enough power to purge the dried grease. I recommend changing the coupler with one that has a lever to lock and release it. I first purchased a cheaper off-brand grease gun and returned it for a better quality (Dewalt). Dewalt has an over-pressure relief valve! If you have a clogged Zerk fitting the over-pressure relief protects your hands from a burst hose (an important safety issue). I wish it had a place to park the grease fitting when not in use. ... show more
