Query: Works Amazingly!

I got this mute because I play the viola and I plan to continue playing into high school but not actually FOR the school. Practicing at home can mean trouble for me because I like to have my window open and my mom likes to take naps. Now, with this mute, I can practice WHENEVER I want to. IT'S LIKE MAGIC. It really cuts down the sound and gives out a beautiful dampened sound. Trust me, you'll want to practice all day long if you get this mute. GET IT!!!
