Winnowl Index
Winnowl Verdict
The PowerSmart 80V MAX 21-Inch Brushless Self-Propelled Lawn Mower Performance ranks 28% below the average and earns it a MEDIOCRE (57) Winnowl Index. The Fair Value and Average Brand Strength can't make up for the deficit created by the Mediocre Performance. For example, the Total Run Time comes in at 35 V, which is below the class average and may mean you will likely be able to mow a typical front and back yard on one charge without having to stop to find a charger. Avoid the Mediocre Performance of this product and take a look at other Battery Powered Self-Propelled Lawn Mowers that are more balanced with their Value and Brand.
