Why didn't someone think of this before?
When I saw this I knew I had to have one.  I was considering the large but I'm glad I got the medium.  It's not exactly the easiest thing to insert because there isn't much of a taper (for obvious reasons).<br /><br />Nice finish and seems decent quality.  I didn't encounter any issues with rough holes that another reviewer mentioned.  It comes with a little string that you can tie into the holes to make extraction easier but I tossed it.  It's easy enough to get out without that cord.<br /><br />Once it's in, what does one do with it?  That's the real question.  I shall think of something.
