I'm giving this a 4-star review even though I am returning it.  The mower came in a nice, compact box and was very easy to assemble.  I had already raked up all the twigs I could find, so I ran right out and got mowing.  My grass was pretty long, and there are a fair amount of broad-leaf weeds, but this mower cut through them like butter.  I was chugging right along until it chugged back.  I know have a handle-bar shaped bruise on my stomach from the sudden breaking power as the mower was stopped in its tracks by none other than a fir cone.  No where in the instructions or online did it mention cones, and the fir cones are pretty smushy in my neck of the woods, but they were still too dense to mow through.  And they are to plentiful since my property is surrounded by fir trees to pick up or mow around.  Very disappointed as I was super excited about this purchase, but it just isn't feasible for my situation.
