Customers are dissatisfied with the size of the ruler. They mention that it's not square at all, the flat edge at the 90 degree angle is not square, and some of the edges aren't perfectly straight. The sides become uneven after a few cuts, making drawn lines not accurate. Some customers also mention that the coating is thick and uneven, making the inside corners hard to keep on the board.

Precise for its cost

Precise for its cost
See my photo of the triangle test I made directly after opening the package. It's as precise as I'll ever need it for the occasional woodworking job around my house.

I've always used a fixed right angle for my projects, For experienced carpenters I'm sure that's nuts but once I started using this, I can sacrifice my fixed tools for a cheap price.

I tested this against my larger carpenter's square and got a match. Either they are both off by the same degree or they are both square. The ruler is easy to read and has both Imperial and Metric scales. I set mine up for metric as I am using that scale more and more often these days. The ruler came out and went back in with minimal fuss. As a hobbyist, I liked the price why pay more? I am very happy with this square.

I do both framing and finish carpentry, and I use this thing all the time. It’s also black, which is kinda cool. It holds up to being used as a guide for the circular saw when cutting studs square, and has managed to not get bent despite my best efforts. Great price, super pleased with performance.

3.0 out of 5 stars Aluminum isn’t sturdy
Reviewed in the United States on August 9, 2023
Color: Rafter Square 7” + Combo Square 12”Verified Purchase
The speed square won’t last a week without bending in the middle. Both sides of the square aren’t accurate when measuring 90 degrees (lines are askew from each other). I even got this item returned and replaced, and same issues. Probably good for school projects, not for constant use for your job. Aluminum made it light, but it also made it flimsy.
