Product review (5 stars): A washing machine at home for less than the cost of an iPhone on Contract.  Think about it.
About two days after I received this washer and pretty much washed everything in my apartment, I sent a picture of it to the person I'm dating with the caption: "I have a new love now.  Sorry."  It's now two months later, and the love affair is still going strong.

I've read many reviews "complaining" about minute things like the lint catcher being pointless, how long it takes to wash etc., but I've rated this five stars because of what it does for what it is.  It's not the giant Maytag at the laundromat, and if you want that, then this most certainly isn't the washer for you.  However, if what you want is to do laundry in the comfort of your own tiny apartment (I live on the third floor of a Brownstone in Brooklyn) without spending oodles of money on dropping off laundry at the laundromat, or dealing with crowds in a narrow space where you have to compete for washers, dryers and folding space, then you will LOVE this thing. It has changed my life.

REASONS I LOVE THE PANDA COMPACT PORTABLE:
*This washer is powerful!  I have bought the mesh washing bags as others have recommended, and it is the best idea (for those of you having issues with lint -- separating and using the mesh bags solves for that).  You'd think that as small as it is it wouldn't do much, but it has a very strong agitator and gets the job done in a short amount of time. I recently spilled red wine all over a white tank, pre-treated with detergent, baking soda and peroxide for about 30 minutes and threw in the washing machine and the stain was all gone.
*It saves me from going to the laundromat.  I used to do drop-off service at $12-$15 a pop (this washer will have paid for itself in 4 months or less).  It was "convenient," but after having things lost, or other people's random items being included in my laundry, I was dreaming of a better way that I didn't see happening, and I'm so grateful for this as an alternative.  For many reasons I would wash my own underwear, and still I would avoid the laundromat like the plague. I have a lifetime supply of panties because I'd rather buy more underwear than go to the laundromat, even just to throw my underwear in the washer and come back and pick them up when they're done. (I let them air dry.)  No more lugging massive bags up and down 4 flights of stairs every week and walking around the corner with a massive bag on my back like some weird urban Santa Claus!
*I can use my own eco-friendly, non-irritating detergents and fabric softeners.  I essentially had to use whatever they did in the laundromat even though I would never use those products on my own. I make my own fabric softener (water, vinegar, baking soda and essential oils) and I feel so much better about everything.
*I can take my time. It absolutely takes time to do laundry with this machine, but as another reviewer posted, whatever amount of time it takes is infinitely better than the nonsense you go through in the laundromat.  I hate doing laundry in the laundromat, but the convenience of this machine changes the whole experience for me. I can be naked and do my laundry all day; I don't care about the time.
*I can wash pretty much everything in it.  Like someone said, you need to do smaller loads, which I'm fine with.  I wash all my sheets and duvet covers with ease. The only things I can't wash are my comforters (which I only wash twice annually since I use duvet covers) and large winter coats (again, not frequently washed).  Such items will go to the drop-off as needed (i.e. maybe twice annually).

Those are the main things I can think of off the top of my head, but they're big ones.  The lint catcher does suck, but who friggin' cares?! ***PEOPLE.  THIS THING COSTS LESS THAN $200! YOU CAN HAVE A WASHER AT HOME FOR LESS THAN THE COST OF AN IPHONE UNDER CONTRACT!***  Think about that for a second. Do you know how much you'd have to spend to "set it and forget it?" I've spent WAY more on less efficient or convenient things, and I'm sure you have, too.  This is all about perspective.

My biggest "complaint" is that it *IS* pretty loud, but I've thought of/read about some workarounds for that; all of which still make this washer worth it.  The pros FAR outweigh the cons of this washer (which are few and minuscule), and I am so happy to have it.  I've been telling everyone about it!  If you're a New Yorker who lives in a walk-up and hates the laundromat -- this one's for you!

UPDATED TO INCLUDE INFO ABOUT SOME OF THE CHALLENGES:
Spin Dryer: I just read a couple reviews of people saying the spin dryer was a "joke" because it does not contain heat and doesn't get your clothes dry.  I died laughing as I have NO IDEA why anyone would think it DID that. It doesn't say that it does.  These people clearly didn't read the reviews or watch the video as suggested under the product details because if they did, they would know that it is basically a more advanced version of the spin cycle in a commercial washer in that it gets most of the water out of your clothes so that you can spend less time drying it in a machine, or air drying it.  It's not supposed to get them bone dry.  Further, this thing costs less than $200.  Did you really think it would have a heated dryer?  That's a lot to ask of a washing machine/spinner combo that costs less than $200.
Lint: If you have problems with lint, use the mesh bags and sort your laundry. This helps tremendously.  I had lint galore the first couple times I used the washer, but once I got the mesh bags, it has significantly reduced.  I still see some lint, but it's not anything a few shakes or a quick pass with a lint roller won't cure.
"Shredded clothes": The agitator is quite strong, so again, use the mesh bags.
Noise: If you live in an apartment building, the washer can be loud on the floor.  One way to solve for this would be to use a thick exercise/yoga mat or two.  I wash in the bathroom, so I use a thick bath rug most times.
"Crunchy clothes": I use my homemade fabric softener (water, vinegar, baking soda and essential oils) as well as Borax in the wash. Makes all the difference, even for the towels, and also has helped with the lint (which I see in the washer and not on my clothes anymore).  They still have some crunch, but very little. I'm planning on purchasing the dryer companion shortly!
