What Is Praised
Many posts praise the large, plentiful pieces of herring roe, the texture, and its presence.

Concerns Raised
Several posts say the seasoning is on the strong side. One 4-star review was, as we confirmed in its text, a complaint about a different product from the same shop, “seasoned herring roe,” not a low rating of this product itself.
