These are a must have for MRE's. Yes they can be a little pricey but it beats eating cold MRE's if you have to. These travel very well too and dont require fire either, which I think makes them better than fuel tablets and a travel stove.
I was reading a story about a Hurricane survivor on the east coast recently. For some reason, I never think of being in a bug-out situation when it is cold outside. I think if a person is planning on buying the pouches, you might as well buy these too, just in case it is cold outside when you need them.
If you like a hot meal....
We all know the benefits of MREs, so I won't get into that. What I will get into is the psychological benefit of having a warm meal. A cold day and a cold meal can make your days rough. However, just adding a warm meal into the mix can make all the difference. For that reason, I stock a few of these with my MREs. I don't have a 1:1 ratio of heaters to MREs, but I know that if I need a warm meal I just need to add water and I'm eating a hot meal in a few minutes.
I got these flame-less heaters just to have some extras around. You never know when they might be useful. Very handy and easy to use. I have not done this yet, but I am going to try to use these to heat up water to be used to cook freeze-dried/dehydrated food.
This is very nice to have for a camping trip. It will allow you to heat the MRE's you have.
A must for the case of 24 entrees
This is a must seeing as the case of 24 entrees does not come with heaters. I wish that these could just be bundled together at a special price. Entrees do not have to be heated, but they are much better when they are.
