Summary: Good product from samsung! pros: 1. multipairing - tested with my samsung galaxy and nokia c2 simultaneously 2. good battery backup - 10 hrs for me 3. redial the last call by just single click 4. volume keys cons: 1. Not ergonomic 2. Shorter BT range 3.
Summary: It was possibly a fake product! I already own a same product which i bought a year back from flipkart and it is still working. The Bluetooth device which i ordered now, could be a fake product because of following reasons. 1. It was not charging.
