Zipper helpers

I'm sure I'm not the only one who hates dealing with broken or hard to pull zippers.  I've dealt with far too many broken cheap plastic pulls or pulls that are hard to get to or just tough to get a good grip on.  After trying several products, these Rings have worked great for me.  They're actually sold as key chains but they're made of stainless steel and work great.  If the zipper isn't broken, I just use it to give me more and easier pulling.  If the pull is broken off, it will fit into the hole of the zipper body and replace the pull all together.  So far they've outlasted many of the zippers themselves.  Did I mention they're also cheap?  20 of them for like $8 bucks.  Just thought I'd share.
