This thing works great.  I have used it a couple of times and does much better than the lambskin chamois I have had in the past.  It absorbs much more than the Lambskin and my car was spot free.  The real test was the sunroof on my car where the water tends to pool and leave water spots.  In the past I always had water spots on it.  Not anymore.  Definitely a must have for those who wash their car.  As another reviewer noted, these are at local big box stores for around the same price if you include tax.  I may pick up another for inside the house.
