Product review (4 stars): It's compact, so if your expectations are compact, you will love it for the price.
My mother in law loves the dry-spin feature.. but I'll get to that.

To start from the top.  This is a small-capacity washer/spin-dryer.  As mentioned, it holds limited number of pounds of clothes it can wash.

I normally don't fill the basin more than 1/3 full of clothes/sheets/etc or they get tangled or don't agitate well, but the wash cycle is quick, so it's not a concern.

If you are looking for a normal or even compact full-washing machine, look elsewhere.  You won't get it for this price, so set your expectations realistically.

Next - the lint trap on this is not very good; It's poor to non-functioning really, but I turn my clothes inside out and it is generally only an issue with mixing specific materials together, so I've learned to minimize that.  I would have given it 5 stars if not for the lint problem.  I also put sensitive clothes in the small mesh bags you can buy for cheap to protect more.

So, you put the clothes in - then add water. I like to add water to well cover the clothes.  IF YOU DON'T ADD ENOUGH WATER, your clothes may have some rubbing against the bottom more severely.  Just add a bit more water. I've not had any issues with this.

DRAINING - you do this everytime after.  In the warm weather, I permanently keep this on my back porch, where I can drain off the porch into the grass.  I CAN'T ATTEST to how well this draining feature works into a waist-height sink.  This is probably where people are having issues with leaking.  So while reading my reviews and seeing 4/5 stars, CONSIDER THIS in your purchase.

Next - the spin dry doesn't hold quite as much as the washing side, which could be annoying, but it spin dries so quickly (I do 1 minute per fill) that it doesn't matter to me.

The spin-dry spins until nearly dry/slightly damp.  You will not be able to wring out more water after the spin dry, and on a moderately warm fall day, if you hung the spun-dry clothes, they're dry in an hour or less in my experience.

My mother-in-law LOVES the spin dry.  She likes to hand-wash things and use the spin-dry and likes it more than a commercial dryer despite the capacity being small.

NOTE:

I've had this for about 6-months and haven't had any issues with leaking or other things. Love it, and it works just as well as the day I bought it.
