Query: Warning: Wrong Size fit Sheet. Try it right away

I bought the California King size in October 2009 but never used it until May 2010. Big Mistake. Because I never could imagine that the fitting sheet was queen size even though the flat sheet says "California King". Lesson learned here: Always open your package and try it right away. For the hussle it created, I would not recommend this set of sheets at all.
