Review on Cowryman Saw Gauge - Precision Stainless Steel Tool For Perfect Table Saw Fence Alignment With Dial Indicator (Extension Rod) - Ideal For Woodworking Professionals by Willie Ogunlana

The mount on the dial gauge is not installed correctly for easy measuring. The indicator sits at an angle to whatever is being measured and produces inaccurate readings. This requires some modifications to get as accurate a reading as possible. ebay gladly exchanged the item for me, but the second unit was just as defective.The images of the item are "straight” on the listing and video, but neither of mine were. Don’t know if this is a deliberate deception or an issue in production.The ball bearings also make it difficult to get consistent and accurate readings due to their moving out of position pretty easily. This becomes too much of a distraction and takes attention away from getting a consistent and accurate reading. Basically, there are too many moving variables that interfere with accuracy.If you want complete accuracy you can trust, look for something else. If you want to tinker with this gauge and don’t mind the extra time it takes to get measurements, this will work okay.
