Realistically, that is a starvation diet. Figure it is really more like a 6-8 month supply.
Most of the calories are in the form of starch and sugar, i.e.- empty calories.
Some of it is freeze dried, meaning it will rehydrate fairly easily, but the rice and wheat and dehydrated stuff requires actual cooking. Not that cooking is bad, but it takes fuel, and cooking wheat is not something most people know how to do.
The picture shows some kind of grain mill, but if there is a list of what is in this kit, I did not find it, so it is not clear to me what all is actually included.
Like almost all such kits, it may well have a place in a food storage system, or it may just a gimmick. Before I would spend $900 on something, I would make sure it was suitable to my needs.
My personal opinion is that most of what is in this kit that is of true benefit is the wheat, rice, beans, and lentils. That is all stuff that you can get dirt cheap on your own, and package it yourself, and it will last every bit as long. No need to have it in expensive #10 cans. Plastic buckets, mylar bags, and O2 absorbers work just as well, and will probably take up less room.
The veggies and fruit are expensive and are not really necessary as part of a survival diet. You will not die from lack of sugar so you really don't need fruit in your diet at all.
In any case, I would be inclined to add some vitamins to one's long term storage plan. A standard multivitamin, and whatever other supplements you think appropriate.
The important thing to me is what is it that you are preparing for. Most people want to go out and buy something so they can say they are prepared. But they do not seem to have even a faint clue what it is they are preparing for, or why. Just that in some vague way it is a good idea. I am inclined to agree it is better than nothing, but I think a little focus on the issue is better than just throwing money at it that is probably better spent elsewhere.
