They are the coolest glasses that anyone can get! Also very comfortable! And they stay on your face without any problem! During the week that I had them, i tried to do a lot of jumping, spinning around and running to test how good they stay on your face and I have to say I didn't have to adjust them a single time unless I had to flip them up on my forehead. It is also amazing that it's an AAA battery rather than a charge, so I do not have to wait for it to use it and they include a battery inside the box. I usually kept a couple of extra batteries in my pocket just in case the ones died during an event. As I was using them, a charged battery stayed working for 6 hours without any problem! I think that they were a huge hit! And I am going to order another one for my body.
