This lawnmower is great! It runs on a battery that charges quickly and can be used in this brand's leaf blower, string trimmer, and many other lawn care tools. This saves you gas and the inconvenience of running to get gas before mowing. It is much quieter than a conventional lawn mower and is likely better for the environment. The battery is powerful enough to mow my average suburban lawn and backyard as well as powering my Ego string trimmer without a break to charge. It has a 5 year warranty and additional batteries can be bought separately. This cost more than the average mower, but what average mower comes with such a warranty and runs off of such a cheap energy source? I am very pleased with my purchase.
