I purchased two of these rulers some time ago. They have stayed in my desk drawer mostly unused until recently when I had a project that required the use of the ruler over a several day period..using as a straight edge. Within a few days, the markings on the first ruler were completely gone, so I started using the second ruler. Within two more days the markings were also starting to wear off.
The only pros on this ruler that I can see are durability of the stainless and the non-slip cork on the bottom. But to use this ruler as a measuring device (it's primary purpose) I can't give this item more than 2 stars because I no longer can use it to measure anything.
