I was really surprised when I got this capo and realized how actually smaller and lighter it is compared to, for example, Dunlop Trigger Capo, which I have, too, but that one is for acoustic guitar and I needed one for flat fingerboard. Being so light, there is no feel of extra weight on the neck.
I can easily be put and tighten with one hand. It is tightened only as much as necessary to prevent open string from buzzing. To take it off, you need to release a pressure, but that, too, is a simple one hand operation.
All in all, really nice little capo.
