Product review (5 stars): Not a substitute for line-drying + a non-wrinkle tip
I bought this and Laundry Alternative's Wonder Wash for use in my RV. Along with a portable clothesline, they make a great and space-saving alternative to going to a laundromat. But this way of doing laundry does require all three pieces. (Add a fan if drying completely indoors.)

Just be aware that any spin dryer, including this one, will not actually "dry" your clothes. Instead, it takes out so much moisture that line-drying them has a chance of succeeding, even on not-so-warm days. But thick or heavy items, like jeans and some towels, will still take a day to completely dry indoors unless you get some moving air around them.

With the spin dryer, you can actually suck so much water out of some garments, like tee-shirts, that you will set wrinkles in them that will not come out while they're line-drying. So now I put things I don't want to wrinkle on the top, so I can take them out before I finish spinning everything else.
