Product Review: GemRed Plastic Multi-Function Angle Finder

 

This is marketed as usable for physical therapy to figure out range of motion. What I used it for, and what I personally think is the best use for it is for math and/or engineering students who want to use it to draw accurate angles in their notes or on homework. If you are in geometry, trigonometry, or engineering classes like statics or dynamics or any similar classes in which you are going to be working with angles a lot, it is very helpful to keep the lines and angles in your work looking nice. I would not describe it as something that is absolutely necessary for a student but definitely can come in handy.
