I m not sure what kind of information you are looking for. I've had a tube for three years and will have it for the rest of my life. The last replacement was the newer button type which I like better than the "hanging tube" type. I use Jevity and other than coffee and chicken noodle soup broth thats about it. Most liquids (and I mean thin liquid) doesn't taste good. I just accepted the idea and have learned to live with it, I still go out with family and friends but just order coffee. I have traveled extensively with it. Some things in life just can't be changed, the sooner you accept the idea the better off you are. I have always taken the thought if thats the worse thats going to happen to me I pretty lucky.
