Its good and efficient

Its great to use such devices when u want to teach efficiently. I am very happy with the product and even my colleagues are amazed by it, out of which 2 of my friends have already ordered now looking at the product.

A versatile instrument for addressing public

Flexibility of movement of microphone is little less and for a relative big size head circumference, head band is little small!

Trustable product

Product is good as expected.Would recommend it.But I would have been more happy if the price was less
