I bought this product because BlueAnt makes quality products usually, but the &#34;Sliding microphone shaft&#34; broke. It will not stay in the unit, it just springs back out. The unit powers on when the shaft is popped out, when you push it back in the unit powers off. So the fact that it is broken, means i can't power it off. It being broken is not because I was rough on it, the fact that you power the unit on and off by moving the microphone piece means that it gets a lot of use.If you are looking at this product, I would recommend another BluAnt speakerphone, without the sliding microphone piece.
