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

So I was browsing Facebook Marketplace and found a Milwaukee M18 FUEL 1/2" High Torque Impact Wrench with two 5.0 batteries and a charger for $150. The guy says it's barely used, looks clean in the pics. I already have a Dewalt 20V setup but this seems too good to pass up. Should I grab it? Is it a good deal or a red flag?

I've had that exact Milwaukee for years. It's a beast - snapped more than a few lug nuts off with it. $150 with batteries is a steal if it's legit. Just make sure you meet the guy in a public place and test it out. Bring a socket and see if it clicks. Also check the date code on the batteries - if they're old, they might not hold a charge.

Hold on, DrillMaster. You're a DeWalt man, why are you switching teams? Ha! But seriously, that price is about half of what that kit goes for new. The M18 Fuel is top-tier. I'd say jump on it, but be cautious of counterfeits - there's a lot of fakes out there. Look for the serial number and maybe run it by a Milwaukee dealer if you can.

I don't do much automotive work, but I have a Milwaukee impact driver for woodworking and it's never let me down. For that price, you could sell it on eBay if you don't like it and make a profit. I say go for it. Just don't tell your DeWalt, she might get jealous.
