There are a lot of people and companies "out there" who are selling "survival food". While most of us know that we need to be wary of the "ours is best" hype, do we really do our research before we make a purchase from a company... I mean do we really look into who they are and the details of what they are selling? Here is an example of a company that is spending a lot of time, effort, and probably money selling themselves and their products, but the reviews do not match their hype.
Here are numerous other reviews of a host of such companies. These reviews seem to be done by people who believe they are possibly going to really need to use the food someday, hence they seem to take their assessment of the long term food supplies very seriously.
