The contact faces of the spring loaded heads could have done with a bit more roundness to make measuring internal bores easier. Also you have to be carefull not to overtighten the lock barrel as it can alter the measurement slightly, but once you get used to the feel of them you will know what's best. This is not a high quality tool but sufficent for most home use applications.
