How it compares in Party Supplies
Across the 49 rated party supplies products we track, the typical score is 4.5 out of 5. This one sits at 4.1, which is in the bottom quarter of the category. That does not make it a bad buy, but there are better-rated alternatives on the same shelf, so it needs another reason to earn your money.
It carries 5,399 ratings against a category median of 948. A rating from a large base is harder to distort and tends to hold up over time, so a high score here means more than the same score on a new listing.
On price it sits in the upper third of a category running from £2.50 to £40.95, where the midpoint is about £5.99. Paying above the category norm needs a reason beyond the rating, because the score alone does not justify the gap here.
