Very happy with this purchase. The range is incredible. I have it on for at least 8 hours everyday and have not had a problem with the battery. Some other reviews mentioned the small on/off button and volume control, this is not a problem with me. I turn it on in the morning and keep it on all day. The volume control is all the way up, this is not a problem. The 3 earpieces all work fine, probably too fine - I still haven't found one I like the best. If I do walk too far away from my phone (40 feet) when I come back into range it automatically reconnects. Great Buy!
