Review: Great Ruler for Math Students - I'm a Math Tutor for Teens, grades seven through high school. I give this ruler to all of my students when I start with them. It has inches and centimeters, and a protractor. For most students, the clear flexible plastic works great. For others, metal is appropriate. I like the clear plastic bc it can be used on laptop screens too. Great tool! I use them in my home also.
Review: HA! Surprisingly Accurate - The Good - This little ruler / protractor is surprisingly accurate! I wasn't expecting too much for the price, just wanted it as a general sketching tool, but then it helped me discover that my $100+ precision carpentry square wasn't really "square" after all. I couldn't believe it at first, but then I went and checked it on a machinist's precision reference square and sure enough, my expensive square wasn't 'square' and the sub-$2 ruler was not only square, but also more accurate. The (very minor) negative - This thing would be a grand-slam if the increments were in 16ths of an inch, rather than 10ths of an inch (which is neither metric nor SAE / imperial). Even if it was metric it would be okay, but 10ths of an "inch" are really only useful to a draftsman (machinists measure in 1000ths). Anyway, very handy little ruler for all kinds of stuff, so I highly recommend!

### ⭐⭐⭐⭐⭐ Does a great job at a great price
*by D***K on March 28, 2022*

This is a convenient device for measuring angles and small lengths. I got this to throw in my to-go box of drawing and sketching tools. The only downsides are 1 - the markings are printed, not etched so, it'll wear off eventually, and 2 - it's difficult to read because the device is so small. But, size, weight, price are what makes this so good. (My pic has shadowing & isn't the best - printed markings are nice & sharp.) It's for occasional use, not daily heavy duty use. All in all, a good buy.
