So, I've read all the reviews here (even useful ones) and it did not help me to solve the connection problem. Blue Tooth is connected but we ran a scan and they told me it's not connected. Then when you try to disconnect and connect the device it disappears on the phone and I have to start over. Of course I wouldn't recommend it. Spend a little more and get a better one (like Fixit)
