The set consists of several different components, but I mainly bought it for the snake/string to clean my bugle with.
FIrst of all the string was too short for my small bugle, and it was very diffucult to get through as it wasn't "stiff" enough, and simply bent. It barely went through, and when I pulled the string, it snapped - even though I barely used any force at all. I had to get parts of the string out with tools. Have to buy a new set, I suppose.
The other parts of the kit works fine.
