I haven't had that much experience with capos, but this seems like a really good first capo. It's well-build, the tension doesn't let go after a while (not sure if that's even possible, but still, it's a good thing).
The only downside, which might also be a general issue with capos is that at first, I got the feeling that'd break when I put it on and attempted to clamp it on. But it got eaiser after a few times. Might've been it needed to be used a couple of times to soften up, or it could've been me getting used to the amount of force needed.
Anyway, a great buy if you're thinking of a getting a capo :)
