Product review (5 stars): spins most of the water out
I love spin dryers and this one works pretty well.  The hardest thing is getting it balanced so that it can get up to speed.  The first several times I used it, I couldn't get it past ~250 rpm and thought I would have to return it.  You just need to rebalance it, sometimes several times, before it works.  And when it's up to speed, you can tell.  It's very quiet, smooth, and fast.  Like the other comments mention, it does seep water.  Keep a rag nearby for clean up.  Mine does wobble when it starts and slows down, but hardly moves even one inch.  I don't think it will fall off the counter.

I love this machine.  I can't imagine wringing heavy wet clothes out by hand.  I am able to air dry anything in my apartment in just a few hours.

Note that it is quite tiny.  I wash my towels in it, but I feel like even one bath towel is pushing it.
