Finally ran across the new 300 lb-ft. version of the Ryobi 1/2" Impact. Decided "what the hell" and picked it up.
Ran around the property a bit testing it out on lugnuts (car, F-250, car trailer, Farmall Tractor), flywheel bolts, motor mount bolts, lifted up the car with the emergency scissor jack, etc. So far love it. LED's come on before the anvil moves, and stay on for a 5-7 second period after you release the trigger. I let it hammer a bolt on as tight as it could and it had no issue removing it (unlike the 1/4" Hex Impact Driver, which is forward torque bias since it's designed for driving screws).
I'm heading up to my parents next week to work on their cars so I'll have a chance to really test it out. Plan on doing a little write-up/review afterwards.
