Review: Good quality scale rule - Good scale rule, markings are clearly marked, can't fault it
Review: Great product - I studied architecture at undergrad and it is very useful for this, it has most of the scales we used bar maybe one which was easy enough to work out using the other scales. As a student i travelled a lot and as a clumsy person I dropped it a lot so I can say that for a plastic ruler it is very durable until if course you try using a scalpel with it... that did not end well for my 1:100 scale but it still worked for measuring, just not for drawing straight lines. I had a metal version which was better for cutting but not so great for everything else. This product is very light compared to it's metal opposition, even the aluminium sort. It also doesn't make a horrible clatter and clang when you drop it in the middle of a silent studio. So yeah, great buy, great price, I would 10/10 recommend.

### ⭐⭐⭐⭐ Good product
*by C***S on 8 October 2025*

Came in a nice crinkly paper package. The first feel of it was very plasticky as if there's maximum friction. Overtime, when it became slightly more oily from my hands, it became smoother. The corners do need to be sanded down though. Overall, it looks like a good tool. I'll be using it in my building Surveying course. So far I've just used to to trick my sister into thinking it changes colours.
