Product review (5 stars): I really like this unit
I purchased this from Walmart, and ran four loads my first day.  Having a washer in my actual apartment is really a game changer, and I can already tell that it's going to help keep my apartment much more tidy since I'll be less likely to let the laundry pile up.  So far, I really like this unit.  A few things to note:

1.)  I'm about 5'8 and fit, and found this unit to be pretty heavy and awkward to move due to how bulky it is.  Yes, it's portable in the sense that you can move it and that it can attach to a sink, but it's not something that you'd want to regularly move into a storage closet.  The biggest drawback is that there aren't wheels on this unit.  It seems like such an obvious addition, since it'd make moving the washer around so much easier.

2.) I'm not the savviest with tools, so it took me a good 45 mins or so to get this all set up.  Getting this initially connected to the faucet was a little tricky.  I actually had no idea that you could even remove your faucet's aerator, so initially I thought the faucet adapter was the wrong side and ran out to the hardware store until an employee told me to remove it.  Make sure you have a wrench to do that part.  It was just a minor convenience, and I'm sure people that are handier than I am could easily figure it out.  Once I got that all sorted, the unit was really easy to use and does a fantastic job of cleaning the clothes.

3. Some people have mentioned that their lid isn't clear, but mine is like 50% clear, so you get a good view of how it's washing your clothes.
