I just bought the 1/2" new one, love it. Did a 6.4 last week, did the head bolts with ease both pulls, I still mark them with paint too since I have the memory of a goldfish and might forget where I was even if no one stopped me to ask questions. Snap on guy says they were told to pull away and that torqueing beyond the rating will not affect the wrench. The angle feature is nice because you can rebite in a pull and the wrench keeps track of where you are in the rotation. And yes, I did check it against mechanical methods and it is as accurate as my eye can detect...
