Here is a review of the pivothead video recorder eyewear by engadget written by Terrence O'Brien 4 Jun 2012.

"Having tried any number of rugged and first-person video recording options, we were initially a bit skeptical of how the Pivothead would stack up. The sensor was smaller, the pixel count lower and the price higher than many of its theoretical competitors. But, we were pleasantly surprised with them -- despite our initial hesitation over their aesthetics. Image quality was occasionally inconsistent but, when when it was good, both detail and color quality were far above average. What's more, operating the glasses is simple and intuitive... so long as you're willing to accept the default settings."
