Everything works as advertised with this wrench. It's marked N-m and ft-lbs. My only negative so far is that you can't hear a click at the lower torque ranges, you have to look for the head to snap if you want to torque at the lower settings.
Regarding the other reviewers issues. I agree with the one poster who said it's hard to determine which increment you're on with wrench. You are always a small bit below when you get to one of the torque scale marks (or is it high :)).
To the reviewer who couldn't move the wrench past 30ft-lbs, that is because there is a lock nut on the bottom of the wrench that you have to loosen to get up higher. This nut is retighten when you get to your desired torque setting. I though the same thing when I couldn't move the wrench past 70ft-lbs, but I loosened it up and it went all the way up to 80ft-lbs as expected.
Also, it seems some people's wrenches are marked in inch-pounds, I recently got my wrench an it only had ft-lbs and N-m, so they may have change this or it may vary depending on which you get.
