Product review (5 stars): Convenient and Easy!
I opted to move to an apartment much cheaper than my previous and it was the first time I found myself without a washer and dryer. So for entire first month, I washed panties by hand in kitchen sink and bought new outfits whenever my clothes became unwearable. So.... there's nothing negative I can say about this portable washing machine.  It's 1000x better than what I've been doing, and it washes far more than just undergarments.

It's super easy to hook up and get started. The instructions suck and make it seem difficult but YouTube it and watch a video. It requires minimal preparation.

The hoses are flimsy and cheap and I've seen other people getting crafty with garden hoses and such but it's not necessary. The hose included works. You just need a kitchen or bathroom sink faucet that is narrow. The opening should be an inch in diameter, roughly.

The main complaint is that it takes forever to fill it up with water (and you have to do it twice for one load--soapy water and clean water).  But you can get a fairly large load of laundry done in one cycle. I did the first load today (as soon as I received it) and I did 2 skirts, 2 pants,  4 shirts, a few pairs of PJs, panties, and socks in one load (about 2 armfuls of clothing).

The spinner dries it fairly well. It's still damp when you remove the material but it's not dripping or anything. I stick it on a laundry rack and it's dry overnight.

Honestly, it's convenient and easy. Best purchase I've made in a long time!
