Excellent
Works well. But read the instructions

Accurate and easy to use
Excellent item, very well made and accurate. I was confused by previous review suggesting one side was 3/8. It is not, both ends are 1/2 as you would expect. Recommended.

Works Well
Does what it says on the tin. Takes a bit of playing with to work out how it actually works but I kind of got there in the end. Decent value but how long it will last I don’t know. Not as good as a decent full fat torque wrench but then again it’s at least half the price of a decent one, therefor 4 stars.

Great tool for non critical components.
Very nice tool. Took this into my work place as we have a calibration station for checking various other torque tools for calibration. And this acdelco was showing between 5% and 10% of the indicated torque value. So the adapter is over torquing. Now I understand that there’s a bit more that goes into calibration and a bunch of other factors will affect the torque value which is why we have tolerances. As I am only using this for diy vehicle repairs I am quite happy to give this 4 out of 5 stars as it does feel like a pretty quality product. But if you need more accuracy then do not use this for critical items.

This is my second digital torque gauge,only used it a couple of times but at least it works and beeps, more then I can say about last one(different type) Seems accurate enough

Accurate and was able for 350nm
Tested it against my teng tool torque wrench at 110nm and was spot on. Next set it to its highest of 340nm but needed 350nm, I went over it and recorded my highest torque of 352nm
