I had a 1 and a half nut I needed to remove. 160ft lbs. Had a Ridged 1/2 in impact. Would nor budge it. So I bought a new ridged 1/2\inch cordless impact, the new brush less one. Took it right off, I was impressed!
Have heard that is a good one...The Dewalt 1/2" impact I use at work is the only tool from them I have been impressed by in recent years. No complaints on that one... I hope to get a Milwaukee 1/2" impact in the near future if I have available $$
