Its legit.
Naa I have always used electric mowers. Easy to store, light weight, maintenance free, and my lawn is small so i dont need to be mobile. I almost did buy a battery powered one but the blade was a 14" I felt that was a bit too small even for my lawn.
Another reason is my neighbor sometimes asks me to mow their lawn. I tell them my extension cord isnt long enough lol they look at me and just walk away. My mower does take a bit of man power since it isnt self propelled, I got to push that shit myself
