I have been through a few Bluetooth devices, and some have worked great and other simply suck the bag, every time I have one that works great on both ends, then 6 months later it stops working, well most are still warrantied so they usually replace it, the issue is since it is 6 moths later they usually don't make that model and usually send you a comparison and never works like the one you have, so I wanted feedback from experiences as I am using a Motorola H730 which simply sucks, I can hear great but people do not hear me good, they have replaced it 3 times, I had the 715 prior and loved it, it had the mic on the boombox and not the unit itself, this 730 has it on the unit and does not come close, here is a chart I found also scroll through the forums, click HERE
