Review on Starrett Graduation NIST Traceable Calibration Certificate by Aaron Franklin

At first I thought it was a good tool. Dropped them about 6-8 inches on the workbench in the first 3 days. They are NOT resettable, they cannot be opened for reclocking. When closed, zero equals plus or minus 5 thousandths. If you don't mind paying that amount for a measuring tool that is accurate to 10 thousandths of an inch, then go for it. THIS FIXES A $30 PAIR, MUST VOTE IN THE Trash! If you look at this product, it says the measurement accuracy is +_ 0.001". That's not true, mine is only good to 0.01".
