## Description

Product Description

Review: Breaks easily: do not buy - I really liked this product and what it had to offer. Unfortunately, it easily breaks. It is made with cheap product so it does not stand up to the quality that is need to use it. I even bought a second bc I did like it when it worked. But even the second one broke just as easily.
Review: Finally heard without screaming - I bought this for gym time with 50, 6 year old kids. It was great. I could lead them in activities and everyone could hear me. Easy to use, and perfect for projecting the voice without damaging the vocal cords. I even used it when my throat was sore and I couldn't talk very loud. No problem. Kiddos heard my reading the story and giving directions with ease. They love it when I wear it.
