Product review (5 stars): No more quarters!
Watch the video review for this product.  It's really quite helpful and will give you ideas on how you can get a system going that works for you.  If you buy this, get a system you can live with.  As much as I encourage looking at someone else's review, here's my 2 cents.

Key points:
*The hoses are short, particularly the drain hose.  Where you use this has to be within several feet of an outlet, a couple feet of a water source and pretty much right next to where you want to drain it.  You can get around the hose length by using a bucket to add water (fill the bucket in a sink or tub and pour water in - the machine is indifferent to how the water is added, since that's a manual process anyway - the hose is a suggestion, not a requirement) or drain into a bucket or tub.  Using buckets involves lifting a couple gallons of water a few times during the process, so sinks and drains are far more convenient.  If you have the included hose too taut, it's more likely to pull off of the faucet, and that means water all over the place.  I end up putting it in front of my bathroom sink and drain it into the toilet, as the tub is just too far away from the sink to make it convenient otherwise.
*You need to put it on something.  It uses gravity to drain and the drain hose is at the bottom.  I use a side table purchased for $12.  It's rated for 30 pounds, which technically this is going to exceed when in use, but the weight is evenly distributed and shouldn't cause even a cheap little table to collapse.  Elevating this by too much might make it harder to use for shorter folks (might be hard to reach in to get things if it's on an actual counter), but leaving it really low could cause some back strain.  Find a cost effective and comfortable height that fits YOU, and remember that you'll have to interact with it a few times per load.
*You may find it stretches some of your clothes out or causes some items to pill.  Use laundry delicates bags.  They sell them in various sizes, and you want to use one big enough to let the garment move around, or put a few articles in the same bag.  If you use a spin dryer, you can put them in the dryer still in the bags or take them out.
*There's no magic rinse cycle or spin cycle like on full sized washing machines.  You drain and refill or rinse separately (you can do a few loads of wash in the same water if you'd like to - I don't pay for water where I live and we're not in anything close to a drought, so I'm okay with using a little bit more detergent to use fresh water every time).  I typically run with detergent for the full 15 minutes, drain completely, refill completely to rinse (I may let it sit in the rinse water for a few minutes or even run the machine for 5 minutes or so if I think the clothes are more likely to retain detergent), drain again, and then have a second rinse with fabric softener if I choose to use it, during which I run the machine for 3-5 minutes to make sure it's distributed evenly.  After the final drain, I wring each item out and then finish off in a spin dryer then hang to dry for a few hours.  I keep a cheap colander with the laundry stuff to use to hold items between rinsing and putting them in the spin dryer, and have also used it for rinsing items that I pulled out before I put the fabric softener in.  It lets things drip dry a little bit, which helps prevent unbalanced loads in the spin dryer.
*Capacity is several small items, or one larger item with really small items.  I've washed full sized sheets (flat in one load, fitted in another).  Adult pants can be washed with other things, depending on size (I'm a ladies 12 and I can get some shirts in the same load).  A bath towel is a large item.  Socks and other things like that can always go in with a large item.  You can fill as much as can move decently well in the water, with the water level about 2/3 up.  If you fill it more, it might splash out the drain hose.

Laundry is more involved than tossing in the washer and then in the dryer, but it's more convenient for those of us who can't have full sized machines.  It's not too loud, but it's not silent.  The timer ticks, the motor isn't super loud, but you can certainly hear it, and the water sloshes around when it spins.  It's probably comparable to the dishwasher in my apartment, maybe slightly less noisy (my dishwasher is loud, though).  This may be TMI, but I use reusable menstrual pads and it got one of those completely clean (after a pre-rinse under running water), so it certainly cleans sufficiently.  I'm not running to the bank to get several rolls of quarters and can do laundry when I feel like it, not when my neighbors don't feel like doing their laundry (or just leaving their laundry in the machines...).
