Compared to a classic "spring" clamp capo, its main advantage is that the screw can be adjusted to finely tune the pressure needed , just enough to make all the strings ring clearly, not too much to avoid sounding too sharp. A big plus in my book.
Thanks to its small size it does not get into your way when playing, like my previous one could do especially on the lowest frets.
Works equally well on my acoustic and the couple of fender electrics I own.
Easy to put in place, it feels robust and should last. I would make the same purchase if mine gets lost.
