Cheap
Cheap for a reason, 3 of the ends were bent which interfered with the straightness and coloured lines not stuck properly. Returned.

Good Product
Wasn't sure what to expect with this being aluminum...have had my old white plastic scale for over 30yrs and was worried this was just going to have the numbers/increments only painted on. They are engraved w/ paint. Very happy with the quality. Now, I just rec'd it today but I would recommend this scale over the ones you get as a 3 pack for $5 more...they are only painted on. The engraved increments makes a big difference when you are working with pencil or marker for accuracy and longevity.
