## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality scale rule
*by J***Y on 15 December 2025*

Good scale rule, markings are clearly marked, can't fault it

### ⭐⭐⭐⭐⭐ SCALE RULER
*by D***N on 19 January 2026*

GREAT PRODUCT AND SELLER

### ⭐⭐⭐⭐ Functional scale ruler but a bit delicate
*by A***W on 15 July 2020*

Functional scale ruler, useful for reading plans especially if parts are at different scales. The range of scales covered on the ruler is very good, and the different colours on each side of the ruler help when switching between scales. It is a bit plastic and feels quite delicate, i don’t know how long it would last in regular use. Perfectly usable for occasional and beginner use, but store carefully and don’t drop as the pointed corners are delicate, and If they get damaged it’s not a lot of use. Worth noting no storage case provided. Good value for the price. Helix make an aluminium version also available from amazon of this but it’s nearly twice the price, but worth considering if you need a more durable option.
