For those that work in a profession where you need your hands free and both ears available, this product can be made to clip nicely to a lapel. Very handy for work where one or more parties may need to hear the conversation simultaneously! It has great volume and clear sound for parties on both sides of the connection. I personally think the power button is perfect. It fits flush and out of the way, you cannot accidentaly turn it on/off. Someone complained that the light is to bright for the dark and too dim during the day. Fascinating, I find it is visible in all but bright sunlight, and in such lighting you can cup your hand over it. It is no brighter in the dark than the dashboard lighting. I find no problem with it and spend considerable time using it. Pairing has been easy with multiple phones. I do agree that this product should be sold with an a/c charger. I would like to point out that on many modern vehicles, you can simple move the placement of the accessory fuse to have continuous power to your power port. It might be worth checking the owners manual for your vehicle. I think Motorola did a great job with the product.
