I've bought several capo's over the years but this is the only one that hasn't lost its strength.  It's held up very well and is really easy to use.  Its extremely thin which means you can move it further up the fret to give yourself a little more room.  The grip is excellent and I hardly ever have to readjust it from deadening the strings.  I ordered another one for my son who has had the same experience.  I would definitely buy this again.
