I used these on a two week trip through Europe. It took about 5 to get a decent foam going in a normal sized sink and they didn't leave things smelling particularly great, but they didn't smell bad. More like they left clothes scentless. They seemed to work well enough to get clothes clean for another day of traveling. Woolite packets on the other hand seemed to make a better foam and smell, but also took up more space. Travelon's item makes a good product for traveling light.
