The wrist band lock seems rather impractical the majority of circumstances that you'd encounter in the aftermath of a disaster or in refugee camps. And the advantage of no assembly seems to be a rather small advantage compared to the cost (a rather bulky construction). The amount of shelters you can put on a truck (http://static1.squarespace.com/static/52e6ca70e4b0aeaf06546dfb/t/54f52911e4b02c0acdf6c119/1425352982937/Shell+carryingFeb10.jpg?format=1500w http://static1.squarespace.com/static/52e6ca70e4b0aeaf06546d...) seems to be quite little. I like the techy look and the idea seems cool, but it also seems to look like a very technocratic approach to shelters. This might work well for first world countries that have to deal with the fixing shelters after a disaster when conditions are quite good. But I can't see this helping out afters disasters like the one in Nepal.
