Wanted these to use for tool storage in my woodshop, so I searched the internet for best prices on these Nite. BatteryJunction price was very competitive and fine for me. In addition to being great the obvious (hanging/storing keys), I'm using mine to provide neat hanging storage for tools. They fit nicely over ¾" - 1-½" cheap PVC piping with the short pieces of pipe fastened to wood ceiling joists (with inexpensive PVC hangers). This provides a clean & neat instant hanging tool storage option for all my workspaces where I want hanging tools close by (e.g over the table saw). They are rugged with durable spring closures, The large circular metal ring really cannot easily be stretched out, so they will last a long time. Was so happy with product's quality that I purchased quite a few that arrived in several shipments. Though there's many options for hanging tools, having a series of these rings on overhead PVC pipes gave me a storage solution (with the 'technical look I wanted) in a cramped workspace. Great product! Haven't even started organizing my keys...

Very useful key holder.
