For 25 bucks I wont send this back but to use it successfully I have to keep in my hand up close to my mouth when speaking. Listeners complain that they cant understand me and ask me where I am when I try to use it clipped to my visor.I have to constantly monitor the volume as well, too loud on some calls and too low on others.Its better than holding my phone up to my ear but didnt exactly eliminate the use of my hand, which is what I wanted to accomplish.
