Great product exactly what I was looking for but heed the warning on the outside about the packaging!  I would use 2 people to help you unwrap it!  I moved away from it as far as I could to cut the packaging off but it burst open and smashed my ear!  If I had not read the package and been a bit closer and looking directly at the package it probably would have smashed my face or broke my nose or worse because I wear glasses!
