The bluetooth works great the mic is pics up what it needs to and not everything else. The earpiece with the mic attached is made of hard plastic and not everyones ear is shaped the same. The top and back of my ear started to ache to the point I could no longer use it. I used another mic tube to run the earpiece to my ear like typical set ups. I have the mic down at my top button and it works flawlessly. ThIs would be perfect if the unit would charge properly every time. I have to plug it in and out several times to get the red light to stay on and continue to charge. I have to check it after 2 minutes or so to see if it is still charging. I have tried different chargers and 7 out of 10 times it won't charge properly. I am sure this is a faulty unit and there is a one year warrenty so hopefully Motorola will honor it even though it was purchased on eBay. The price is ridiculous if it charged and proved to be durable I would recommend it. This is my third bluetooth purchase for use on police radios this would be the best one by far for clarity and battery life if it would charge properly.
