Anybody who has worked in a prison or a jail knows how loud it gets in a cell block. This ear piece is a must have for anyone who works a block. It is true that the product can break somewhat quickly but Galls and the company is good about replacing them. It keeps your inmates from hearing your radio traffic and you don't miss important calls. It takes about a week to get use to having it in your ear after that it's hard not having it in. Must have for anyone who works corrections!
