those things absolutely suck, dont get one, just get a gas mower
after about 2-3 months you'll need to buy a 2nd battery, after that a 3rd one, then a 4th
my parents had one of those and I went thru all 4 batteries and only got half the job mowed, and I used a riding mower for the big stuff, just used that battery one for around the house, trees, flower beds, etc...
it takes hours to recharge a battery for 10-15 min of use
