Liquidraw Rulers RR30 Editorial Review
The Liquidraw Rolling Ruler is a versatile tool aimed at artists, architects, and engineers. The varying customer experiences suggest a mixed reception of the product. One user found the ruler to be flawed, noting that it appeared crooked and was not straight. However, another customer appreciated its precision for marine use. Despite its precision, one user mentioned an issue with the rolling feature, which affected the direction slightly, causing some inconvenience. In summary, the Liquidraw Rolling Ruler has received both positive and negative feedback. While it offers precision for marine use, it has been criticized for potential flaws in its straightness and some issues with the rolling feature.
