How it compares on the fish & aquatic shelf

We track 50 rated fish & aquatic products, and the middle of that pack scores 4.6 out of 5. This one is on 4.0. Bottom quarter of the shelf. Not a red flag by itself, but similar money buys a better-rated option here, so the case for this one has to come from somewhere else.

9,012 people rated it, where the shelf median is 3,120. With that many opinions behind it the score won't move much, and it is difficult to manipulate. That is exactly why volume carries weight in our ranking.

The shelf runs from £2.11 to £29.98 and the midpoint is about £9.49. On price, this one is in the top third. Paying above the middle of the shelf needs a reason the star rating does not supply, because on ratings alone the extra money is not buying an advantage here.
