Works as expected, not perfect the ruler was slightly bent (very small amount of bend) but was able to straighten out easily. This is not a Starrett but for the price it works very well, it locks tight and is easy to read. I bought this so my welder would not have to use my Starrett on the weld table, don't like scraping weld spatter off $150.00 hand tools. For woodworking and general fabrication this should perform as good as the high end combination squares though it may get dinged up and wear a bit faster and easier.
In Florida most metal rusts
No rust with stainless steel
The 16 in rule makes it easier to mark wider boards
Easy
Works great with a marking knife
And has a nice marking pin built in
