They are OK if used in very late fall thru early spring, on the snow, othertimes expect all kinds of rodents and insects to gnaw right thru the green outer bag while you sleep and leave you to deal with the falling-out mess. Pack your feces in a hard plastic or metal can while you sleep, or better yet, put them (tightly packed) inside your sleeping bag, so no creatures get to it, otherwise you will be left with dripping shit on your way out. Or, just ditch the regulations and go without. Unless it's better thought out, it's not going to take space and weight in my pack any longer.

...by the Sequoia National Park. Does not stand to its hype. It's just a plastic garbage bag with some powdered odor neutraliser inside. You poop in it, try to wrap the top somehow and bring it down the mountain or out of the wilderness. If you have to poop again, and you will, open it up and add to the day-old mess you created. And then put it inside your sleeping bag for the night, so as to limit access of curiously hungry mountain creatures. No, thank you. I will just bury it in the soil 6 inches deep next time.

It's a very nice concept, with the vacuum packaging for very high elevations. However, it will only work at elevations over 16,000 ft, below that, the regular packaging works just as well, even from the sea level, and packs more stuff for the money.
As for the taste, it's ok when you just need to stuff yourself with some dehydrated junk food after a day of climbing, but the meat in it tastes like dog food. And looks like it too.

Great taste, but make sure that you stir it really well from the bottom when you add water and then let it sit for a little bit longer than recommended wait time. It makes an awesome recovery meal as well as a good power breakfast in the morning for a 35 mile push. Taste is very real, you don't even tnink dehydrated, but instead think of an Olive Garden. Just let it sit for a while before you dig in.
