Query: The BEST thing since Sliced Bread!!

I am disabled and have a hard time mowing my lawn. I have a self propelled mower but, I do not walk fast enough to keep up with it. This Robo Mower has made my life so much easier!!! It does a fine job and never gives me ANY PROBLEMS! very simple and easy to opperate!! just put this mower in the front lawn and push the green button then walk away!! Thats IT ! I LOVE THIS MOWER !! I was worried at first because of large rocks and trees in my lawn but, the RoboMower performed Fine!!
