It's a farcical "review" of Haribo Sugar-Free Gummy Bears.

At some point, it was determined that the sweetener (or something) in these, caused ... adverse ... reactions, in some folks.

If you look at all the reviews for that product, you will see many more, but this was the prize-winner.

Actually, I suspect that the ratings went to a different (sugared) product, or that Amazon moved the products around, so the ratings applied to something different.

The sugar-free variety was the problematic one.
