Product review (3 stars): 3 stars... it's neither crappy nor amazing... it's OK.
I bought this item back in May (while still living in a house with a W/D), and used it for the first time earlier today in my new apartment.

I have it set up in my bathroom, on a folded up bath towel to cut down on any vibration and catch any minor leaks.  I set up the drainage hose to empty into a 10 gallon bucket, so I could potentially reuse the wash water for a second load.

My first load was 10 T-shirts, with enough water to fill it to the M line (~8 gallons of warm water; filled by hand with a small bucket from the bathtub faucet, plus 1 T laundry detergent). The wash cycle seemed to work fine.  Drainage was a bit of a problem, because I discovered that to fully drain the unit, the unit should ideally be a few inches above the end of the drainage hose.  Although I could drain about 3/4 of the water into my 10 gallon bucket, the last bit required draining into a shallow bowl (repeatedly dumping and then letting more water drain).  This was slightly annoying.

After the wash and drain, when I attempted the rinse cycle, nothing happened.  I discovered that I'd blown the circuit breaker on the outlet.  Not sure why that happened (it didn't happen for my second load), but after re-setting it I kept a closer eye on it.

The rinse water I drained into the bathtub (still needed the shallow pan to remove the last bit of it).  The water still seemed a little grungy, so it made me wonder how clean, or well-rinsed, the clothes really were.  I hand-wrung 5 of the T-shirts and added them to the spin basket (the second 5 shirts would be the next batch).

I was actually pretty impressed with the spin cycle.  After only a couple of minutes, my shirts were still slightly damp, but nothing that a few additional minutes of hanging in Arizona's low humidity couldn't quickly finish drying for me.  The noise and vibration of the spin cycle was noticeable but not terrible; I couldn't say for sure if my next door neighbor would be able to figure out that I have a mini washer.

Final thoughts: It took about 16 gallons of water (8 wash and 8 rinse) for one load, and probably about 15-20 minutes (the draining issue of filling and dumping that shallow bowl seemed to add the most time).  Elevating it on a platform or low countertop would make draining easier.  For future attempts, I'd also probably like to try to add clean water to the spin inlet (oddly enough, not mentioned in the instruction book) during the spin cycle to insure my clothes were well-rinsed.  I'm not entirely sure the washing agitation is that much more effective that just stirring the clothes by hand in a wash basin, although admittedly a machine does save all that physical labor.  All in all, if I had a W/D in my building instead of having a 1/2 mile walk to the laundromat, I'm not sure I would have spent the money on this.  I miss my full sized W/D.  Nonetheless, this Panda does do what it's supposed to do, so far (day 1).
