Review on General Tools 300ME Precision Stainless by Jerry Frey

ruler scale is very thin and light making this steel ruler exceptionally difficult to read unless the available work light reflects the ruler at the right angle. In practice this means that you move the workpiece and the ruler and try to find that narrow corner so that you can read the ruler. The gradation is almost invisible if the working light is not perfect. However, very fine graduations allow very accurate readings in good light (compared to rulers with too thick graduations).
