I don't trust.
Markings are wrong, same size listed for both go and no go. Don't bother.

Not worth the money.
Min and max are exactally the same. 1.4636. How is min/max exactally the same? Made in China crap!

Accurate, 2 no-go guages
They are both no-go gauges. One is 5.56/.223 and the other is only 5.56, they are accurate. Give one to a friend? Keep the extra in a range bag? Misplace one? It's up to you.

Marked but not correct.
Marked min and max but both were identical. Tried in multiple barrels to verify. I should have read the reviews before purchasing but it is what it is. Returning for refund.
