Product review (5 stars): Great washer, but not portable really.
Not really portable, because it is rather heavy, but does have a carrying handle on each side, so that helps. The hose it comes with is rather short, but if you buy a garden hose at home depot, you can lengthen the distance between your faucet and the washer by screwing one end to the faucet connector, then the other end to the included hose. Make sure you connect the correct end to the washing machine, because if you try directly connecting the hose and not using the included pipe at all it will leak. Also, don't forget to use the little wire clip to connect the drain hose ... because if you don't, it's definitely going to leak.

Just did my first load of a laundry in it last night, and it did a great job! You just leave the faucet on the whole time, and it'll leak water out when the washer isn't using it, then when the washer needs it, it's there. Surprisingly quiet. Also has an awesome spin cycle ... I left my clothes out to air dry, and they were dry when I got up this morning.
