Product review (3 stars): Extremely labor-intensive, and effective. Ties clothes in knots. High water and detergent usage. Incredible but fussy spinner.
This appears to be identical to http://amzn.com/B01ICBLBL0, except for minor cosmetic differences. This review is for that machine, which I purchased from Amazon.

To minimize the water-wasting and labor-intensiveness problems, get the large size - typically listed as 11 to 13 lbs capacity. (Don't worry, it is still small and light.) To minimize the knot-tying problem, always use small washable laundry bags!

This is obviously meant to be used in a bathtub or shower. The inlet "hose" is completely useless (but might make a fun drinking straw), and the gravity drain hose is only long enough to get the water to the floor. The only way to fill it is with a detachable shower head, regular hose, or a bucket.

PROS:

* Clothes get cleaner than from any other regular consumer-grade or laundromat washer you've ever used. Seriously.

* The spinner is far more effective than regular washers. (Thanks to a much smaller size and correspondingly lower mechanical demands, with significantly higher RPM, and overall more angular momentum.)

* Very fast. You can get a a wash/rinse/spin/rinse cycle done in less than 20 minutes.

CONS:

* Extremely labor-intensive! You have to move the clothes no less than NINE times between dirty clothes hamper, and dryer! (Load dirty clothes into tub for wash, move half of washed clothes into spinner, remove spun clothes, move other half into spinner, move spun clothes into tub for rinse cycle, move half of rinsed clothes into spinner, remove spun clothes, move other half into spinner, move spun clothes into dryer.)

* High water usage for the amount of laundry capacity it can handle without choking.

* Ignore the people that say you don't need much soap. For typical soil levels, you need 1/2 to a full capful of liquid detergent.

* If you put too much clothes in it (more than 2x spinner's worth of dry clothes), it will grind and fail to circulate clothes properly.

* This machine ties long sleeve shirts, pants, and straps into knots that Houdini would struggle to undo. (You MUST put those items in wash bags, or your clothes will literally be one big knot and won't get clean. The smaller the bag the better, otherwise the bags themselves get turned into knots.)

* The spinner is EXTREMELY fussy. Getting it properly balanced is a nightmare, no matter how few clothes you load in it. (And it won't work if unbalanced - instead punishing you with a loud, slow banging.) On the very rare occasion that you get it balanced right the first time, you may be prone to audible, giggling, as if you just won the lottery.

Overall, I'm happy with the machine. Although it is difficult if not impossible to keep up with laundry for a small family, it is still a little better than the laundromat grind. And my clothes are the cleanest and cleanest-smelling they've ever been!
