Got one of these myself. It's definitely an upgrade from my cheapo $5 nameless capo as strings don't buzz and ring out even if I put it on an electric guitar with different radius.
It's not the cheapest it's ever been on amazon but cheaper than all retail music stores I've seen so far
Bloody nice capo - replaced a couple of spring based disasters that put way too much pressure on the strings. Easy to use one handed once you get used to it.
