We are very pleased with the appearance, quality and comfort.  The elastic is strong enough to hold it on the 18" mattress (and that's hard to find).  These are a very good value for the price.  The only negative was when we saw the "Made in China" on the packaging.  We'd gladly pay more to support U.S. jobs.

Pros: Great value, strong elastic, good appearance, good quality, comfortable.  The white set is very pretty.  :)
Cons: Weird color choices, not enough color options, made in China :(
