How it compares in Bathroom
Across the 22 rated bathroom 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 20,767 ratings against a category median of 7,386. 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 lower third of a category running from £3.00 to £32.99, where the midpoint is about £11.00. Buying at the cheap end is fine when the rating holds up; check the specifics below rather than assuming the saving is free.
