I haven't seen a review for this anime yet. It's suprising but this anime gives valid information for what you should do if lost. The anime itself is average with quite a bit of fan service and little character developement but every episode they give valid information about what you should do in a stranded situation. Its generally upbeat, and each episode completes and the end. So if you don't mind a average anime with fan service and want some good information if you happen to get stranded I recommend it.
