My daughter and her friend marched for the summer with this and it worked just fine.

My daughter loved it

Daughter used it for marching band this season and worked great--held up to the "abuse"!.

My daughter loves it

My daughter used it for marching band season and it never failed!

This is my daughter's first year in middle school band and she loves this

My daughter found it easy to use, it fit her well, and stayed in place.
