5.0 out of 5 stars Reviews were right, just buy it.
Reviewed in the United States on April 30, 2017
Style: Grease Gun + 20V Battery (4.0 Ah)Verified Purchase
The other reviews on this grease gun were spot on. This was a very expensive investment for me considering I used to use the cheap $20-$40 pneumatic grease guns. However, this was worth every cent, and I hope it lasts a long time for the money I paid. Because it is cordless, I was able to grease my tractor implements that were sitting away from my garage where my air compressor is without having to move them. Hence, I was able to grease everything at once and be on the same schedule. The fact that you can simply hold the trigger and it keeps putting out grease is amazing compared to any other grease gun I have used in the past. This saves a lot of headache when reaching into very tight places. The hose is very long and allows you to get into places cheaper guns can't get to easily. The tool is a bit heavy but the strap that comes with it solves that issue, plus it keeps it out of the mud when conditions are bad outside. The purge valve on the top made for a very easy install of the grease tube. My only other complaint was that the pull rod was EXTREMELY difficult to pull out and lock because the spring was so tight. I had trouble holding the grease gun from moving while pulling on the rod. I expect this will get easier over time as the spring wears in from use.

I bought the kit with the case and battery. I would recommend it unless you already have a bunch of the bigger batteries and faster chargers around. It comes with the larger battery and the faster charger which was grease since I already had some of the smaller 20V batteries and a slower charger that I got with another Dewalt tool set. The bigger battery is great for the other tools like my reciprocating saw. The case for the grease gun is very nice and has a depiction of where the hose is supposed to be routed in the case to make it fit. Overall a nice design, and worth the extra money for the case and accessories.

Overall I look forward to never messing around with another broken grease gun that doesn't have the power to push the grease out, and never purges right. This tool was expensive, but I agree with others that it was well worth the extra money spent.
