You Need a Lav Mic in Your Life

Do you make videos? Then you probably need a lav mic in your life. I bought one for a project I was working on, found out it didnt work for the project, and forgot about it. Today I'm getting it back out for another try.

The key here is that the closer to you the mic is, the better you will sound, or at least thats the theory. Does it work well enough? Will this allow me to turn my head and still be heard just as well? Was it worth the $50 I spent on it in the end? Why does my face look like that?
