How it compares in Gardening
Across the 39 rated gardening products we track, the typical score is 4.4 out of 5. This one sits at 4.4, which is around the middle of the category. Ratings alone will not separate it from its rivals here, so price and the specifics below matter more than the star count.
It carries 16,900 ratings against a category median of 4,311. 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 middle third of a category running from £2.29 to £31.99, where the midpoint is about £8.99. That is the part of the range where most sensible buys sit, neither cutting corners nor paying for the name.
