Handy in a pinch! But more of a rinse+ or a wash-
I bought the Scrubba bag to accompany me on a 42-day journey through Africa. It was a long trip on an Overlander bus that involved camping for 33 of those nights. The Scrubba bag came in very handy since packing light (just two pairs of long pants) was a necessity and laundry facilities were regularly two weeks apart. I needed to be able to wash a pair of trousers and let them dry overnight. It worked great. My only criticism would be that it needs to have scrubbing fingers throughout the bag since once the bag is closed, turning and twisting clothes so that they touch the washboard was difficult and, in the end, a waste of effort. In the end, I could do only one or two items at a time and I wouldn't exactly have called them clean, so much as not dirty... rinse+? Not to be misunderstood, the scrubba was a godsend on a this trip, but I wouldn't choose it over washing in a hotel sink if a hotel sink were available. When facilities are lacking the scrubba is a great option!
