## Customer Reviews

### ⭐⭐⭐⭐⭐ Does angle torque!
*by J***E on February 5, 2024*

This is perfect for doing angle for head bolts and crankcase bolts. As long as you're starting torque is 25 ft lbs or more, then you can use this and it makes it so easy!Batteries going out will happen. Get some higher quality cr2032 batteries. May have to undo one bolt, re torque, then do angle again if this happens.I recommend this over an expensive digital torque wrench and those terrible angle gauge toys. Unfortunately for me, I have a warped head in my case, but this makes things easier when I do again soon.

### ⭐⭐⭐⭐⭐ Quality item. Arrived in good condition.

Quality item. Arrived in good condition.

### ⭐⭐⭐⭐ Worked for me
*by K***D on December 2, 2021*

The media could not be loaded. I can not confirm accuracy but it come with calibration cert. Can be set to about 4 or 5 different units of measurement. Track or highest reading settings. I'm keeping it. Time will tell it holds up.
