I've been putting up with those fabric and plastic based capos for a long time now (don't waste your time with them). This is a very different thing. Most importantly it enables you to place your capo directly on to the desired fret without any twisting/movement from the tightening, so you get a really nice firm and even pressure. This is essential to make the intonation work OK, especially if you're moving the capo on and off during a live performance.
Otherwise it's solidly build and east to operated. Totally recommended!
