How it compares in Mowers & Outdoor Power Tools
Across the 46 rated mowers & outdoor power tools products we track, the typical score is 4.4 out of 5. This one sits at 4.6, 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. That places it third of the 46 we rank here.
It carries 11,035 ratings against a category median of 2,539. 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 £3.99 to £1028, where the midpoint is about £69.99. Cheaper than most while rating at or above the category norm is the combination worth looking for, and it is the main argument for this one.
