Query: Motorola Battery-powered bluetooth headset

This is an excellent product especially for someone like myself who travels a lot. I don't have to haul around a charger. The reception seems a bit weak at times so it's important to keep have a fresh battery. But the device will give many hours (>20 hrs talk time)of quality sound until the weak battery becomes a factor. Overall this is a very good product.
