Mouthpiece Buzzing Tip : Buzzing on Incentive Spirometer!

I got this idea from Denson Paul Pollard at International Trombone Festival. This tool is really useful to make better sound.
호흡기를 이용하여 공을 올리는 버징연습
호흡을 제대로 사용하지 못하는 초보자들이나 볼륨이 작은 연주자들을 위한 최고의 연습방법이다. 모든 금관악기에 적용이 가능하며
호흡기의 레벨은 자신에게 맞게 조절하여 사용한다.
공을 띄울 수 있다는 것은 악기를 불면서 호흡이 제대로 나간다고 볼 수 있다.

How much does it cost? And where I can by it?

When you buzz with the spirometer you are just practicing buzzing really really loud. Especially when you have it on the higher settings. How is that good for you're playing? Isn't buzzing softer better for buzzing?

Hi I recently got a spirometer and I was wondering what you did to fit the mouthpiece. Did you cut part of the tubing off and attach the small piece you cut off? Thanks!

I like to cut it, but sometimes I use a long tube too. A Longer tube needs more air ;)
