Cork came loose after a few uses.
Unfortunately one of the corks came loose after just a few rehearsals - and on concert day! Fortunately I had my trust Humes and Berg Stonelined piccolo mute with. I had feedback from the rest of the brass section to say that they preferred the tone of that one also. I do like the look of the TC copper mutes but this one did not seem to be reliable for me.
