Plastic is good quality and feels like Dyson plastic. Not all attachments fit into the slots as tightly as you would like, but they don't hang around or fall out. Also, the spacing between the slots had to be slightly larger and this would give more room to accommodate the different fastener heads so they didn't bump into each other. I'm not sure why they made it so tight. I can't tell how well it will hold up over time once attached to the drywall with dowels. We installed ours on the inside of a wooden closet door. The door is solid wood, so I suspect this item will remain strong for as long as we need it.
