This was it my first. It bothers me, however, that the official cutting edge is not quite square that I often then but "ripped" next to my cutting. And in this scale is raised slightly so that not necessarily 100% accurate cut even here is possible.
I would recommend it conditionally on.
I'm a perfectionist, look around in the future but time for another ...
... Or so I thought. Even now more than 2 years after purchase of the ruler I have still gained no other cutting rule. I'm now very well with it. And I resigned myself to the shortcomings. With practice, I have fewer problems.
And it is not worn. Looks almost like new.
