Avoid this product like the plague. It is so horribly designed that it makes me wonder if they actually did product and usability testing. Ok, ok so here's why: 1. the wire from the phone to the device is too short, causing you to have to keep the plastic device near the phone at all times, 2. the retractable wire is TOO SHORT, it needs to be at least 12&quot; longer, 3. the plastic case has a 'hang up' button that constantly rubs up against things and drops my calls (!). If those aren't reason enough consider that the earpiece falls out constantly becuase the mic either gets caught on things or swings the device out of your ear. What a waste of money.
