This is a well built and thought out machine. It performs almost flawlessly. Light weight, easy to use without fuels and oils. No rope to pull. I am 76 years old and need self propell. I don't need for it to lock up at its own whim. It locks up in a straight or curved line. Now I read that the speed dial must be turned all the way down. So I am to stop, turn the speed up and then squeeze the lever. Otherwise a well made machine

Pros:Incredibly lightweight and maneuverable.Doen't need gasoline obviously.Cons:Seems to clog up too easily unless it's on the highest setting compared to my last gas mower.The claims about being more powerful than gas mowers is likely based on a specific statistic like torque but in my real world experience this hasn't meant much, im guessing there is no flywheel to keep it spinning under high resistance.**The ejection port pops out too easily leading to running it over if you were currently pulling the mower backwards - furthermore I cannot find the correct replacement part only one that is painfully similar, yet does not fit.I purchased it from Lowes and they said their protection plan wouldn't cover the ejection port since we let it fall off. The whole experience has not been a good one considering how much it cost.
