Gewa Mute Tourte Double Bass

Bought this to make practicing a little more considerate of those around me. Only to find that this "mute" doesn't do anything other than act as decoration.

It's bulky, so you'll think it's gonna do the job, but it doesn't. It's a pain to put on (compared to the other mutes available) as it needs to have the strings fed through it and then it flips over the top of the bridge. That's where it just sits there. Pizz, no difference in volume with no dampening at all. Arco, again, absolutely no difference at all.
