Query: It does exactly what it is supposed to do!

And I am very glad it does. Have wanted to have an adjustable end wrench which I did not have to keep tightening each time I took it off-and-on several times in a row. It is sturdy and precise. The locking mechanism is easy to clamp and loosen. My only need is for a set of one smaller and a "miniature". This would be perfect!
