What to know before buying
Listing details to confirm
The listing is inconsistent about construction: the details table says Metal, while feature text says Carbon fiber and ABS. It also lists a 200 Millimetres graduation range but separately claims an angle measuring range of 0-999.9 °. Confirm the intended material and measurement specifications before purchase. The stated accuracy depends on placing the ruler horizontally and resetting to zero before measuring.
