Accurate and made well
These are a very good set of gauges. Nice thickness to them and accurate to a T.

Good stuff
A nice set of gauges. They're thicker than they might appear (they're not flimsy) and the radius is clearly marked. Well worth the price, a must-have for any guitarist's toolbox.

Great Product
Better than the plastic ones I was previously using.

Accurate and intuitive
The understring radius gauges are so far the best tool I've found for setting a guitar's action, in combination with something to measure the top and bottom strings to start you off. It takes a lot of tweaking, but if you set the strings so that each one is buzzing on the radius gauge, I don't think you'll find a more accurate setup. I'm talking very minute turns of your saddle height screws to get everything right. Although it takes time, this process is easier than measuring the inside strings against the frets, as well as being more accurate.
