Works as described once I figure out how to use it. I got it wrong at first, so I contacted the support team, they sent detailed institutions to help, but I'm not very good with written instructions. I learn best when I see they sent a very helpful VIDEO guide and I tried again and they worked perfectly. Actually it was just 1) there are 2 buttons, one on the right shoulder of the sunglasses for the bluetooth function and the other on the bottom edge for the camera function. 2) also only the right micro usb is a charging port, it is marked with a charging symbol and takes 32gb.
