I've opened the ticket #59573 a week ago and no response so far.
The item is not working and I'm realyy surprised there is nobody in your company who can respond.
The Sonof Dual doesn't want to go to pairing mode. The blue led slowly blinks one time and repeats. When I press the button for seven seconds (or more) the blue led still blinks one time and repeates (no change). I'm not able to pait the device and not able to use the device at all.
Please respond to ticket #59573
Looks like defective item. Discussion with ITEAD how to resolve it.
