I have been ordering them for 2 years but until recently they were from another catalogue. That listing has disappeared, so I searched and found this one with the same product (same brand, #s match, etc.). But unfortunately this is not the right product. The worst part is I'm assuming this is a new form of my favorite product judging by the dates on it. The gel doesn't go from edge to edge anymore, they're thinner and don't stick as well (meaning they don't last as long). I will look for a new approach to the brand unless someone declares it all as a big misunderstanding.
