Review on Irwin Tools 1794484 Aluminum Level: Precision and Durability for Accurate Leveling by Matthew Goyette

I bought 3 levels for my project because I received levels that were not calibrated at all. The only working plane was the Irwin plane. It passed the test by reading the same thing no matter how I shot it. Seems well done. The only caveat I have is that if you push the string hard (by hammering the peg deeper) the level of the string will drop. But it saved my project - I needed a good level NOW!
