How it compares in Baby
Across the 50 rated baby products we track, the typical score is 4.6 out of 5. This one sits at 4.8, which puts it in the upper quarter of the category rather than level with it. Where almost everything is rated well, the gap at the top is small in points and large in practice.
It carries 1,613 ratings against a category median of 1,103. That is enough of a base to take the score seriously without treating it as settled.
On price it sits in the upper third of a category running from £1.99 to £30.90, where the midpoint is about £11.65. It is priced above the field and rated above it too, so the premium is at least matched by how buyers rate it.
