The Wonder Washer
This is a so-so machine. And having looked at a lot of these portable washing machines, this one is probably just as good as a lot of them. But, basically, it is still a lot of work, and won't do very much in a single load.
You can fit about a day's worth of clothing in here, so if you're on the road and need to travel light, you could stick this in your trunk and then bring it into the motel room each night for a load. But otherwise, washing your clothes everyday is kind of a pain.
It is electric, which some are not, so it is easier than using one that you have to hand crank. But there is no water hookup, so you have to fill the bucket by hand, which is difficult if you don't have a large sink or bathtub to use. Worse yet, when it's done, you have to dump out the water by hand. And when it is full, it is pretty heavy. Then you have to hand rinse and wring the clothes, piece by piece. So, like I said, this is a lot of work.
If you really need a portable washing machine, this is probably a decent choice, as good as any other. But, as you can probably tell by now, it doesn't really thrill me.
