It works really well but, plan ahead to have good scissors around to open the package. For something like diahrrea, you would think this would be easy to run and get to, that is not the case. The little line where you're supposed to tear open, is not tearable in any way upon close inspection. You need to cut one side near the pill, while making sure not to crush the pill (have had that happen thrice so far), nor that the pill will pop out rolling away into the abyss (twice), and that you cut enough to be able to pull at the indestructible backing to get to the pill. Is this backing material used in the military? I don't see how this was approved by anyone. I literally can tear bookboard apart with my own hands and open the toughest jars but, these little packages have torn open the skin on my fingers with 0 progress to reach the pill.
