Product review (3 stars): It dries.  Sort of.
I've used this dryer for a month now, and I thought I'd share my reasoning for purchase and my observations thus far.

Reasoning:  I recently downsized to a two bedroom apartment with limited capacity for a washer and dryer.  In fact, almost no dryer capacity.  I purchased a second hand washing machine that barely fit through the door and wanted to avoid having to take wet clothes to the laundromat.  In addition, I'm somewhat eco-conscious as well and the reviews/videos I've seen of these dryers made me really want to try taking one... for a spin.  (Groan)

Setup: This is light.  I had no trouble hiking this up six stairs and then back down six stairs to it's location.  I can carry a forty pound bag of dog food if I strain, but I'm not a burly guy.  Setup was... confusing.  You definitely want to make sure you take the brace out from the bottom before you start it that prevents it from spinning and damaging itself during shipment.  There are warning stickers.  I didn't pay attention, but caught it very quickly before I damaged the unit.

Impressions:  This does dry laundry.  I've tried it with two scenarios.  The first was damp laundry out of a HE spin washer from my laundromat and the difference was negligible... maybe a cup of water out of a single wash load.  The second scenario is out of my old school top-loader.  This removes easily a gallon of water from that load and gets the clothing... to damp.

Buy a drying rack.  You'll need it.  For sure.

When I say load, I'm saying wash load.  It takes me five separate spin loads to clear a washer load from my relatively small washing machine.  My process is to do a load in the washing machine, split it up into five groups with something heavy on the bottom of each for balance, and then I do other household chores or hang laundry during each of the 5-6 minute spin cycles.  If you balance the laundry well, it will come safely to a halt and you can grab each load when it's done.  If you overfill it or unbalance it, it threatens to topple over.  I never dared try to see if it actually would.

Verdict:  I can't really do bedding.  It's a little tedious.  I'm not sure how it will do in a humid summer.  I'm not prepared to go back to the laundromat. Yet.  I recognize that some folks might pair this with hand/tub wash, and I think it would make a great companion to that approach.  I'm not here to defend or recommend my approach, just to describe it, and how it works or doesn't work at the moment.
