Wow! I finally noticed the prices - $400 for the duo and $300 for the solo. They should be able to make a profit.

Almost anyone should be able to find roughly 50% of the items within their existing stores, especially if they do anything outdoors. It is trivial to improve on their items in many cases - I would prefer a one quart repurposed sport drink bottle (and even more) to their small container since capacity is everything. As Montanero pointed out in his recent thread, water is pretty critical, even in a flood. Their protective gear is reasonably decent, but lacks head protection. A construction grade hard hat is better than nothing, but I prefer (and stock) helmets designed for caving and climbing - much better protection. One could go on.....

One good thing about the kit - their pry bar is equipped to turn off gas - good job!

I prefer, especially for earthquakes, the recommendations right here on ETS - http://www.equipped.org/earthqk.htm
