Let's not forget that some of the recent Sino Promise batches of chemistry have been defective in one way or another, including Xtol. In a single order, I ended up with bad batches of Xtol, Dektol and D-76, so I swore off "Kodak" chemistry at that point (about 2.5 years ago).
All of the Kodak-branded chemical products I've bought recently have said on the package "Made in USA for Sino Promise Limited", so they're probably made on contract by an American company for Sino Promise. Poor QA is likely to be the culprit for the issues people have been having.
