I think this is the future, I really wish this was as common as self inflating life vests. I wear one every time I go kayaking, but for the bike we are unfortunately still a ways out. After watching Fortnight's video on them, I think the issue is with the manufacturer. Some want you to send them back in for inspection after each inflation to verify that it's still good or even worse some require you to pay a monthly fee. I think all of this is crap, and the clip in style should be more available for less money. It's not anything crazy, just a Co2 and a release lanyard... I hate the idea of people profiting off of my safety...
