So far so good !
Sticker came right off cleanly, maybe they fixed the problem .. the square itself is really lightweight, hoping it doesn’t dent up easily ..

Easy to read and just the right size for up to x 4 wood
Scale is easy to read and just the right size for small jobs or 1 x 4 and 2 x 4 wood.

Pay attention to the size 4.5"
This is perfect for a 2x4, but I did not note the size (despite being in the description), I went by the picture, as it came up with all the other framing squares. I was expecting the larger square. But nonetheless, it works great for 4" lumber.

Clearly one of the best small squares out there
Super handy size of this square makes it a must have around the wood shop. Love the white on black easy-read markings. The price is right and it seems to be a quality tool. Was going to pay the price for one of those fancy smaller squares, but glad I didn't. For what I would have paid, I could have three of these. Will definitely get another one to have as a spare.

Nice little compact square
The negative reviews about the sticker proved to be quite useful as it gave me the heads up to use a heat gun and the sticker came off rather cleanly. Other than that, good solid little square.
