Pros: Accuracy is square and true. Measurements are accurate. Offsets - easy to measure inside or outside of a square. Cons: Durability - It's not the strongest metal. I could probably bend it if I was careless enough or willing to try. Final Thoughts: This is a great square for the price. When the time comes, I would like to order a larger square from Johnson. I use this all the time and love checking my table saw settings.
