Are they all the same size (radius of hook) or an assortment o sizes? Do they also sell screwdriver and pliers holders?
I buy my at the local Home Depot, so far, I have not run into any problems, anyhow, if I do run into problems I can always return them to Home Depot. They are supposed to be of a standard size so they can fit into the holes. You probably got a "Made in China" batch,
