Of all the capos I have tried, Kyser capos are my enduring favorites. They are very sturdy, are easy to use, and really live up to the "quick change" moniker. This capo fits my 6-string guitars perfectly, and is very powerful, yet quick to reposition (be sure to unclamp it rather than sliding it on the fretboard.) I find all capos to be slightly intrusive, but this one has the least interference of any I have personally used.
