Found a killer deal on a Milwaukee impact - worth it?

So I was browsing FB Marketplace and found a Milwaukee M18 Fuel 1/2" impact wrench with two 5.0 batteries and charger for $150. The guy says it's barely used. Seems too good to be true. Anyone have experience with these? Think it's a fake or just a lucky find?

That's a steal if it's real. Milwaukee Fuel is top-tier, I've been using mine daily for 3 years no issues. Just check the serial number on Milwaukee's site to verify. Also make sure the batteries aren't knockoffs - look for the red ring on the contacts.

Dude that's an awesome deal! I paid $300 for just the tool and one battery. If it's legit, grab it quick. I've used mine to change tires, and it ripped off lug nuts torqued to 150 ft-lbs no problem.

I've seen fakes going around. Check the hammer case - real Milwaukee has a smooth finish, fakes are rough. Also the battery contacts should be gold plated. If it's real, that's a $400+ combo usually. Jump on it!

Thanks guys! I checked the serial and it's legit. Met the guy at a public spot, tool looks brand new. Batteries charge fine and hit hard. Best $150 I've spent in a while. Appreciate the tips!
