Need a cordless impact wrench... Suggestions, please

Had them all Rigid is the way to go 100% guaranteed, and so are the batteries, they go bad they replace them, seriously the thing is a beast!

I have the Rigid 1/2 inch impact, and I'm not sure describing it as a beast is strong enough language.....lol. It has 600 and something ft lbs. of torque in reverse! The lifetime warranty on the gun AND the batteries and charger is what sold me on it.
