I suspect that if you are reading this review, it's because you are trying to justify spending 100+ USD on a square.  Believe me, I did the same thing.  But, after going ahead and biting the bullet, I'm very pleased with the purchase.  It may sound weird to say, but the tool is just lovely.  The surfaces are machined perfectly and it's dead-on square.  Final bonus?  Made in the USA.  You can buy a crappy square made in China and be frustrated with the results, or buy an American made product and have it for the rest of your life (and then pass it on to your son or daughter).
