Considering they are grossly overpriced for pennies of molded plastic, one would hope they are fair. They work. Unfortunately, quality control seems to be overdue, and all the supports in the box have a sheath (foreign plastic) that prevents the mount from being pushed in (see photo). In other words, you can't slide your shelf past the clip onto the support seat where it should be. Working carefully with a paring knife, you can cut off the skin, but this is ridiculous. Modify each prop before it can be used.
