This thing sucks. I have go over the same spot at least three times. Even when I first bought the mower it was not a one pass mower. I would not recommend this to anyone who actually wants to mow their yard. Its good for exercise in that you'll be pushing it around much longer than you should. It also gets stuck on any little twig. Doesn't matter how small. If there is a twig in your yard somewhere you will know about it.
