This is a replacement for a prior Motorola bluetooth headset of very similar design. I was quite pleased with the old one, until after about 2 years when it just died. That was 2 years of daily service, so not an issue. But this new one has issues holding pairing with a Blackberry 8700G, and has significant voice static unless the Blackberry is on the same side of my body as the headset, and not in the holster. The old one didn't have that problem.
