don't you agree they are just rubbish!? I think my cornet makes a great sound (although not neccesarily when played by me) but the valves are terrible. They have been 'sticky' for a while and at one rehearsal one of them just ceized up totally. After lots of turning it upside down and blank faces my housemate noticed the valve is actually bent. Therefore it does't go straight down the valve case and hence gets stuck. I definately haven't dropped it although that was the first question! I have no idea how this could have happened...has anyone found this before?
