Can't easily beat the price of this capo, which nevertheless does its job on both acoustic and electric guitars. It might not be immediately intuitive how to operate it, but once adjusted for the proper tension, it just works, and has a nice diminutive incumbrance compared to other capos.
The only downside is that after a while the strip can slip and the capo needs to be tensioned again. This hasn't occurred to me while playing, but can be noticed in between days, so it is possible that the capo won't maintain tension throughout a whole gig.
Overall, quite satisfied for home/practice/rehearsal uses: 4/5.
