It worked really well. It is not fast, but seems to get clothes cleaner than washing out in the sink. Follow the directions exactly, don't over fill, don't use too much detergent, etc. I carried the filled bag out to by the desk, and used my feet to swish all the clothes around for about 15 mins. I found that easier than bending over using my hands. Rinsing out was fairly easy using the shower, filling the bag, swishing without being latched/closed. I did that twice b/c I hate soap residue. Overall I will bring it again on a long cruise for a few things as needed.
