To be honest, I threw these in the bin.
I have used Magnetic knife racks for holding all my tools to the wall, but sometimes these can group the tools unevenly. I was hoping these racks could be used to line up all my screwdrivers, smallest to largest, OCD compliant etc. Unfortunately these hooks are unable to hold any tool less than 1/4 an inch diameter. Its OK for the big screwdrivers and small spanners shown in the picture, useless for anything out of its narrow range (say 1/4 to 1/2 inch).
The build quality again is what you expect for the price. I would expect a couple of the clips to be broken by the end of the year.
