I have Swanson squares in the 7 inch metal and plastic versions. They are incredibly accurate, each and every one. Do the "flip" test and you will see what I mean. I bought these to use to square up my table saw fence to the table. Worked great. You will find a ton of uses for these things to make sure everything from drawers to shelving units are perfectly square.

Although I’m not building roofs or stairs which I would guess is the most common use. It does very well for marking 90 degree lines for easy cutting with the miter saw or to use as a guide with the circular saw. Very happy with the larger size!

Had a plastic version hit the garage floor. Broke in multiple places. This speed square cost more, but I am confident it will be around for quite a while. Another case of you get what you pay for.
