On the subject: Can someone explain to me the rationale behind taking a product (for instance, I think I’ve seen Twizzlers) and putting a sticker over the OU with not only a different hashgacha but also a different brand name (I believe it’s Oneg in this case)? What is the point? Is that run and only that run certified by the second hashgacha? What’s the point of putting another brand on the sticker?
I can’t speak about any particular case but unless the sticker specifies what added benifits they provide, I assume there are none.
