Query: Best capo ever

If you are a classical guitarist or just enjoy playing on them, this is the capo for you. It is flat and wide like the neck of a classical, so there is equal pressure on each string. Furthermore, the thumbscrew tightening mechanism allows for exactly the right amount of pressure, so you don't have to worry about strings going sharp like you do with a spring-style capo. The only drawback is that it takes two hands and a little time (10 seconds) to put on. However, as a classical player, I never have to move a capo in the middle on a piece. It's either on or off, so this little drawback doesn't matter to me.
