I gave up on them! And yes - I did have a couple that looked 'dull' and didn't stick well despite very, VERY careful application. Blasted things! Certainly didn't work for me, so I'm back on the Estrogel. I also had one from the last batch that was faulty as it had a little black 'inclusion' within the patch glue. Hmmmm.....
Also hated the wrinkling, and the 'surge' on patch day and petering out which is no good if like me you don't have any ovaries! I know for some, these are god's gift - but for me personally, it was a definite no.
Were yours 50's, Anjia?
