Review: Prefect for what I needed. - I bought some of these for work. They are prefect for testing electronics with potentiometers. Many testing specs call for potentiometers to be set to different degrees of rotation, I drilled a small hole in the center for these to slide over the post. They are thin plastic but inexpensive, they are prefect for what I need them to do.

### ⭐⭐⭐⭐⭐ Neat Little protractor compass
*by B***Y on September 19, 2025*

I usually preferred Alvin or Westcott for my drafting rulers and templates. This Westcott protractor compass is a really nice template, only 3-1/2 inch diameter. It's semi-flexible, so it shouldn't break. The only complaint: Supposedly, it was in stock, but took nearly 2 weeks to get it in my hands
