Product review (4 stars): I'd give it 5 stars if it had a separate rinse or spin cycle
I had a Haier 1.0gal washing machine, purchased used, that lasted 3 years of abuse before the motor finally failed. I managed to score one of the Whirlpool portable washers for dirt cheap. It's about twice the size and weight of the Haier, and is about the same size as my portable dishwasher. It's only a little louder than the Haier even though the motor is so much better, but not much and I really only hear it during the spin cycle in my small duplex. There's a loud 'click' when the cycle finishes, no beeps or anything, which I rather like.

Protip: It's a high efficiency unit, and low or no suds detergent should be used. Regular laundry soap will gunk up everything in side rather quickly. Also, Whirlpool sells a stacking unit for this, so if you have the Whirlpool compact electric dryer, it can be mounted above this washer if space is a premium, but you lose mobility because it's awkward to wheel around like that.

I've had no problem with the spin or pump, mine works fine on all cycles. I love everything about this machine. The little cup that holds the powdered detergent is set up so the incoming water goes right through it, dissolving it before it gets onto the laundry, so no more blotchy messes.

My only 'druther' is that I wish it had a dedicated rinse or spin cycle. While you can interrupt a regular cycle by lifting the lid (because it won't operate at all if the lid is up) it would just be nice if there was a dedicated cycle for it for those times when I'm washing a super absorbent load, like sweaters, so I could do an additional rinse to be sure all the soap is out.
