G7th range - I bought one of what they now evidently call the "Performance Capo" when they came out. Works very well, and no problem with it falling to pieces. But I found it easier to use the Keyser, because you can move it round one handed, even in the middle of a set of tunes.

And I see that the "G7th Nashville" they've now come up with seems to have the same basic design as the Keyser. I see on that G7th site they say it is "lighter and quicker to use than the competition".
Which presumablky means the Keyser.

Anyone like to do a comparative review?

(I've never found the Keyser puts the strings out of tune, but some people seem to.)
