This is one of the more personally gratifying products I will get to review. Full disclosure: a high school friend of mine is a co-patent holder on these. So, I am very proud to own and review a pair. Like most of the early adopters, it took a while to get mine. Over a month from purchase to delivery. Once you get your hands on a pair and feel the quality of the build you will see why they take a while to manufacture and are worth the wait.
