Product review (5 stars): The Laundry Alternative Nina Soft Spin Dryer...
I just used the spin dryer today.  Before purchasing, I had viewed a video on YouTube to see how it works.  With my first attempt, I loaded 6 short-sleeve T-shirts in the spinner, not soaking wet so as to not add pounds, but just somewhat wrung out.  There was a lot of shake, so I rearranged the shirts a couple of times (per the instructions to rearrange clothing if there is shake), but there was still a lot of shake.  The six T-shirts did not reach the top of the unit, but it may have been a matter of pounds.  (I had removed the motor locking pin before using.  There was a small crack/chip in the plastic grill on the bottom of the unit, but it did not appear that it would hamper function.)  I removed 2 of the shirts and tried again.  This time, it ran smooth and quiet, and the clothing came out at least 90% dry (no drip at all), which I then just hung on a rack, and they were completely dry within an hour.  Just remember to put a bowl underneath the spout to catch the water as it spins out :)
