Yeah there pretty cool but they have the same problem as the other Electric mowers. The Hustler, Cub Cadet and others that have flopped over the years, there typically to expensive for the homeowner and can't be used commercially. They tell you or claim there capable of all day mowing or up to 5 hours of continuous mow time but in reality all that will vary depending on the terrain your cutting, what type of grass you're cutting, height of cut and how thick the grass your cutting is and the operator themselves and how they use the machine all will play a big part of how long the machine and it's batteries will cut or last. For the cost involved there just not worth the money.
