What are the disadvantages of good day biscuits?

It's tricky to answer this question directly because "Good Day Biscuits" isn't a specific brand or product. It's more of a general term.

To give you a useful answer, I need some more information. Could you tell me:

* What kind of biscuits are you referring to? Are they sweet, savory, crunchy, soft, etc.?

* What are your concerns? Are you worried about health, ingredients, taste, or something else?

Once I have more information, I can give you a more specific answer about the disadvantages of the biscuits you're interested in.
