This Vernier tool is as advertised. It's most important feature, apart from accurate measuring, are its steel calipers. The tool replaces one with plastic calipers that become pitted quickly yielding inaccurate measuring. Another good feature is the on/off toggle switch, large screen and fractions. Added to that is the plastic case for protection in a toolshed in which a backup battery is supplied. All in all it's value for the price. Perhaps a more expensive one is more accurate, so say advertisements, anyway, but this Neiko suits me handsomely for my uses in woodworking.
