This is such a small little gadget that is so easy to carry I can use it frequently and never feel like I am straining my voice, so it makes it extremely easy to keep up with my vocal warm ups. I like to use it for awhile doing scales before I sing, but it does warm up my voice quickly so I can use it for shorter periods if I need to as well. There are so many times that I find it difficult to warm up before going in front of an audience, but I feel like I can do this more quietly anywhere. I am really glad that I got it.
