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 4.5, 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 331 ratings against a category median of 2,539. That is a thin base by the standards of this category, so treat the score as provisional: a handful of extra reviews can still move it either way.
On price it sits in the upper third of a category running from £3.99 to £1028, where the midpoint is about £69.99. Paying above the category norm needs a reason beyond the rating, because the score alone does not justify the gap here.
