Seemed accurate, but fragile
Seemed accurate for setting up my blades and corners on things. Dropped it on my rubber mat from bench height, and now it's bent. Not that it matters, but it bent a lot. I wonder now if it remained square the whole time I used and handled it.

I bought the 4 and 6 inch versions. These Kinex squares are sturdy, well built tools. I checked the inside and outside edges against a couple of other accurate squares and found them to be dead-on. As a bonus, they don't come supplied with some junky plastic case that I would have to pay for and immediately toss in the recycle bin. For less than $20, these are a bargain for squares built to the manufacturer's stated tolerance.

I bought two sizes of these square and they make setup, alignment, and verification of 90 degrees incredible easy. I highly recommend them. Other options with scales are available around the same price point, but they typically aren't even as close to as accurate. I use calipers, rules, and tape measures with these and the pairing works really well.

5.0 out of 5 stars Gives me the warm fuzzies
Reviewed in the United States on August 14, 2023

Did I *need* this square for the jobs I'm doing? Objectively, no. I'm the kind of person who plans and measures and measures again and then botches the cut (or hole alignment, or really anything) anyway. I'm pretty sure when I use it to draw it a plan I'm also doing that incorrectly and somehow skewing the angle slightly.

But I've gotta say there is something really nice and comforting knowing that THIS tool is closer to a perfect 90 degrees as I could ever appreciate. Not BASICALLY or PRETTY CLOSE like my builders square or speed square, but it IS 90 degrees! I have absolutely pulled it out just to show off the fact that I have the standard by which all other right angles should be judged.

Whatever my shortcomings in regard to execution may be, I can always proudly point to this paragon of hypotenusical perfection. It makes me happy to have it in its special little place in its special little box with its special little certificate in my tool box. It just makes this little nerd's heart happy, and at the end of the day that is enough to validate my purchase.

I've only been using this square for three weeks but it has become a permanent tool in my apron pocket. It has been used for marking wood for cutting as well as making sure tools, blades, etc are aligned and square. I was pleasantly surprised by how solid and well made it is. That is a great plus in this age of cheap, flimsy tools.

The square I was hoping for didn’t show up. Instead I got a square that one side is fairly accurate and the other not so square. For everyday use I suppose you could get by, but really I was hoping for the ones that do show up ( as I’ve read) that are dead on. Oh well, that’s the roll of the dice.

I sent it back and bought a $100 Woodpecker. Yeah, lots of bucks but it’s really nice- made in Ohio.

I’m sure the square here is fine and made in Europe. Kind of have a good rep. Too bad.
