Product review (4 stars): Nice spin dryer, be prepared for trial and error while using it.
I've owned this dryer for a few months.  Overall it works great, it pulls about a gallon of water out of a large towel that was just washed.  It can, however be very difficult getting your clothes placed inside so that when it spins, it is balanced.  In general I try to only use it with a few items at a time to prevent excessive wobbling.  Sometimes I will have identical items of clothing placed inside perfectly spaced so you would think it's balanced, but it will wobble and automatically shut off.

It's hard to know where the "heavy side" of your clothing is so you can shift some of the clothes from the heavy side to a lighter side to get it balanced.  It might only take moving one item a quarter of an inch to the left or to the right to get it balanced.  You might have to adjust the clothes inside many times to get balanced enough to run.  If you run it while it is not balanced perfectly it makes a clicking noise.  The manufacturer states the life of the dryer will be reduced if it is run while unbalanced too often, so I put extra time in trying to get it close to perfectly balanced.

After all it is physics, if it's not balanced it will wobble, you can't blame anyone for that.  Overall, I would rather use this dryer than go out to the Laundromat so I give it 4 stars.  Since it uses no heat, you should expect to hang your clothes up for at least 4 hours. Clothing like jeans will still take about 12-24 hours to fully dry.
