Maybe they work better in camping scenarios
I used these for washing clothes out in the sink during a 3 week Europe trip, and they were ok but didn't produce any suds even in hot water. They also didn't get the sweat or cigarette smoke smell out of my clothes, and I ended up using the soaps provided in the hotels instead of these. Maybe they work better in camping scenarios, but I wouldn't use them again.
