I went to a rave in San Francisco and the pictures were really good. Apart from that, these glasses were really heavy. The lens is actually glass so dancing with them is a little sketch, you have to dance like you're Stevie Wonder looking up while dancing and now you're not even looking at the visuals but at the ceiling, just to keep this hangs on. I will be buying lighter glasses for the next event as I lost one of the two I bought at the event.
