Title: Great "Professional" Slide Whistle !
Review: This is a great slide whistle for professional players. If you are looking for a "kid friendly" one, by all means buy one of the "$2.00" plastic ones. You will "not" find a better slide whistle then this one. The slide whistle is a "play by ear" instrument, which a lot of people get frustrated when they try to play along with songs. Some people complain that it "sticks" while playing.. I have not seen that. One suggestion if the instrument frustrates you, you might consider buying an easy instrument.. like a metal Kazoo...
