Winnowl Verdict

Even with the PowerSmart DB2821 Battery Powered Push Lawn Mower scoring an AVERAGE (71) Winnowl Index, the price-to-Performance ratio is a tough pill to swallow. While the Performance is Strong, the thing to watch out for is the Mediocre Value paired with Average Brand Strength. The PowerSmart DB2821 Battery Powered Push Lawn Mower (21-Inch, 80V, 6.0Ah Battery, Brushless) delivers a Battery Voltage of 80 V—which is 77% better than the average and means you should effectively clear heavy brush and thick stalks that would typically require a professional-grade gas mower—but at $399.99, it is an inefficient spend for the Battery Powered Push Lawn Mowers class. Unless you really are glued the the performance, we recommend you consider other Battery Powered Push Lawn Mowers where you aren't paying 52% extra for 16% less value efficiency.
