I've been using these little devices since I first saw them for sale. Their size and shape make them ideal for use with car radios that can drive them. They have a small loop for attaching a lanyard. The ones I use have a 1.5" ring which makes removing recessed bits easier. The main downside with them is that they don't come with the protective cap they originally came with. I would love to see a small keeper that can have 8-10 of them join. I bought 25 of these and only one failed and was fixed by uninstalling and then reinstalling its contents.
