Of all the variations of capo out there, this one is the best I've used. The stretchy band around the post and heavy chrome lever types are too difficult to position but this spring loaded type can be re-positioned with just a squeeze to get away from that buzz or mute that you run into at times or that intonation glitch away from the sweet spot from guitar to guitar. It's not 100% clamp and play but it's better than other designs I've seen. Still waiting on the perfect capo.
