Accurate
Professional quality. Used this to layout a home renovation product for our bathrooms and master closet. Worked perfectly. I did the floor plan and the architect was able to use it to do the rest. Itโs plastic so it might not be accurate if you bang it around, but otherwise fine.

Easy to read and very accurate.
Much easier to read than a standard white scale. The metal construction also makes it much more durable than most.

Good for what it's for
This is exactly what I needed! It's sturdy, well-made, and the measurements are clear and easy to read. I appreciate the precise markings, which are great for accurate measurements, whether you're using it for school, work, or crafting. Overall, it's a simple but high-quality tool that gets the job done!

Its metal!
Cold to the touch for an Architecture student my tools are majorly important so when I saw there was a metal Engineering triangle I got it. I don't have to worry about led and ink getting on it and ruining my drafts. and I don't have to worry about it bending or breaking. I have loved this form the moment I got it. and I love the sounds it makes!
