I have a greenworx (think thats how you spell it) off amazon. Im sure the bigger name saws are even better, but it had good reviews so i gave it a try.
Bottom line, it rips. It has a 16" bar and for a truck/atv, or around the house saw it punches way above its weight.
Just had a friend over and i needed to cut an old 14" fir. Hes from a logging family so of course the eye rolls and jokes are flying. 5 secs later its a shocked face and "lemme see that thing".
Cleared 4.5 miles of old logging road on one charge last year. It looked better than i did at the end. I will say it leaks bar oil like a sieve though.
Best of luck on your choice, seems like current battery technology is killing it.
