Having (apparently) non-standard ears, I was tired of constantly adjusting my earpiece/headset while driving. This is a good alternative, as I hoped it would be. The flashing light is not super annoying to me, but I can see how it would distract some drivers, Part of that is probably the height of your head in relation to your visor (I drive a Honda Accord).I do agree that they should include an AC adapter for home. The provided car charger isn't that practical and is flimsily built. Mine was damaged just by putting it away with a little pressure on the mini-usb style connector.All in all the sound is good and it works as advertised.
