## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect for tight spaces
*by T***S on May 1, 2026*

Nice little engineering square, perfect for measuring “plumb” in tight places.

### ⭐⭐⭐⭐⭐ Small square
*by J***E on March 24, 2026*

Nice small function square. Will work for what I needed it for.

### ⭐⭐⭐⭐⭐ Perfectly square for me
*by T***T on May 8, 2024*

I had been setting up my table saw, miter saw, and bandsaw using a square that I now know to be un-square. After watching a video or two that show how to assess if your trusty square is actually square (of the 4 I own(ed) only one was actually square) I knew I needed something accurate. The reviews on this square are a bit mixed but mine was perfect. Skip over the reviews that complain about the box it comes in, the edges being too sharp or any of the other nitpicking things about it. Read the description and you will find that it is small, so expect small. It's not a big square but it will work perfectly for woodworking tools. Unless you are on NASA's space team, this will do just fine.
