Query: It works . . . and is environmentally friendly!!

This electric mower arrived in a box and took only a couple of mintues to assemble. Just plug in the charger and, a short period of time later, it is ready to work. Be sure to adjust the height function, as it is set really low. This adjustment is easy to do; just follow the directions which are actually in English.The only other comment I can make: mow your lawn in the cooler times of the day. Even this electric mower needs some energy to make it work well.
