The EGO LM2101 is the highest-rated electric-battery mower on Consumer Reports by far. Its lowest category rating is for its bagging for which it is rated “good.” Despite testing the push option the reviewer found this mower was easy to operate and had effortless handling. However they found the 40-minute battery runtime to be fairly short a common issue with cordless electric mowers. Techaeris tested the EGO LM2102SP and found the battery lasted 60 minutes which was long enough to finish the reviewers 1/3-acre lawn. He estimated that the yearly cost to operate the EGO would be $1.50.
The Sun Joe MJ104E has more than 1250 five-star reviews on Amazon. Buyer Jim has had his Mow Joe for more than a year and left it in the weather and abused it otherwise. He is happy with how it has performed. He cautions against buying the 16-gauge extension cord recommended by Amazon. Instead choose 12 gauge for 100 feet or more and 14 gauge for under 100 feet.
