It works great, but has some limitations to be aware of.1. You should store the jerrycan sideways with the water spigot pointed down, so that you can get more water out with less pressure2. You always need to keep a reserve amount of water to keep the filter submerged so it doesn't grow mold. The jerrycan says to leave "two inches" which is great in theory, but in practice you have to guess because there's no way to tell the water level. (This is another reason to keep it stored sideways.)3. I really had to hunt around to find the replacement carbon filters, they weren't sold on Amazon last I checked.4. Refilling the jerrycan requires removing the hand pump. The issue is that you have to carefully balance it on a flat surface so it doesn't get dirty or contaminated.
