| Jesus -- the Lemur product isn't the same exact one as in your post, but it's very similar, it works on the same principal. The screw is a bit smaller on the Lemur version.
My experience with the Lemur one is mixed. It does help reduce the wolftone, but doesn't eliminate it entirely. Like a previous post said, you sometimes have to move it up or down the string a bit. And over time, as the screw starts to loosen, it begins to rattle so you have to retighten it.
