Ranked in these QuestionsQuestion Ranking
Pro No food contamination
Since it's made of 100% food-grade stainless steel, you can be sure the food will not be contaminated with plastics, nor will the environment.
Pro Shock proof
If you drop them for a few meters, they don't get warped. Perfect for excursions to hilly trails, where you might just drop them accidentally.
Pro Super compact and well laid out containers
It is perfect for backpacking(as long as it doesn't hold any liquids).
Con It can rust
Even though it's made of stainless steel, some users on Amazon have noted that it can rust a little, so you need to keep it dry as much as possible.
Con The covers don't fit well
On most boxes, the measurements of the covers are off by millimeters, making it a less than ideal fit.
Con Not ideal for liquids
Since it doesn't have plastic seals, spills can be troublesome, so it's best used for solid foods.
