Review on HORUSDY Organizer: Top-Quality Holders for Optimal Efficiency by Martin Dosunmu

They are not durable. I had them one day and I've already broken 3 of them. The other big problem I had is that getting the heads off the 3/8 inch holders is very difficult. I have to pry the bushings open with a screwdriver to keep the 3/8" retainers from bending and breaking. Damn. They look really cool but are more of a toy than a solid tool.
