Don't be without one!
GREAT item! I purchased it for my new trumpet, because I live in an apt building & I'd like to have the freedom to practice as long and loud as I choose yet keep peace with the neighbors. At first, after trying this again & again I was ready to return it, when I suddenly realized that one of the connections was not in tight. What an amazing tool!!! HIGHLY recommend it. I don't think anyone playing the trumpet should be without one.
