This is great for the strange application for which I purchased it... After a cycling accident that resulted in a shattered elbow that now doesn't straighten, I needed a solution that consistently gives reliable measurements over time as I try different elbow straightening techniques.The 2 armed protractor allowed the accurate placement of 2 x 1cm black lines on my outer forearm & outer upper arm and a pivot dot on the elbow by a neighbourhood tattoo guy. The little holes (fabricated at the centre point and along the arms) in the protractor enabled the tattoo chap to plot precisely where to tattoo the required lines/dot.Now, with those tattoo marks, I can overlay the protractor, lined up against the tattooed lines/dot, and then see changes in the arm's bent angle...

I purchased this for a college mathematics course and I love the fact that I can fold it and it’s compact.

I think it is much too expensive for what amounts to a flimsy plastic ruler. I was expecting something more sturdy for the price. It's decent enough to keep, and I like it as a drawing aid, but if you're wanting something more substantial look around before choosing this. It shows 2 objects but there is only one.If you haven't found anything, I'll tell you the pros: pretty clear, nice holes for drawing points where you need them, and the measurement lines are clear. The corner allows you to measure angles pretty well.
