Specs absolutely matter. Incline of your lawn, outdoor outlet location, type of grass you have growing. I’d never recommend a plug in electric lawn mower to someone who needs to mow six acres of hills.
That said, electric mowers by and large are better for most consumers.
I’d give for free if they gave it for free. They rip people off for the stuff I freely gave? No, I’ll take a few bucks out of their profit, thanks.
Besides, I usually can’t donate anyway but I give that shit all the time when I can. Especially when I know where it’s being used (for free.)
