How it compares in Mowers & Outdoor Power Tools
Across the 50 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 1,649 ratings against a category median of 2,618. That is enough of a base to take the score seriously without treating it as settled.
On price it sits in the lower third of a category running from £2.99 to £220, where the midpoint is about £59.00. 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.
