My mom wants an electric lawn mower. Any reccomendations?

My gas mower had to go in for repairs so they lent me an Ego. It was not ergonomically good, I couldn't get it adjusted to make me feel right mowing with it! You had to grab two different controls to keep it running, you release either one and the mower stops, made it tough when switching hands to make corners like I often have too. It was earlier this year, hopefully they corrected the issue as I would never feel comfortable using it like it is. It did have enough charge to do my lawn which takes around 45 minutes to mow...
