Listing pictures are misleading. The Bluetooth/intercom units mount to the side with poor quality double sided tape, whereas in the images it makes it appear to be fully integrated into the helmet. I looked closely at the pictures prior to purchase and the inability to see the BT unit hanging from the side was a major factor in my decision to purchase. I messaged the seller, have recieved no response. If I wanted a cheap helmet with a low cost BT attachment I could have spent half as much money.
