Not bad to put together.  As one person said, it was easier to look at the picture on the box and apply logic.  Being "assembly challenged" it took awhile, but I got there. Felt pretty good about it. I then went out to mow.  Surprisingly it was easier than trying to start my gas mower, no bag to empty and then try to get on again, I do have a smallish grassy area in the front and side of my house, but even with twigs and leaves I encountered little problem.  In fact, if I'm honest, I felt good.  It was easy. No noisy motor or fumes, no worry if you have gas in the tank, perfect for me.  I live in a wooded area, don't have the perfect lawn, but it suits me fine.  Easy enough to do twice if you need to.  I love this thing.  I'm a retired female with a total hip replacement.  Best therapy in the world being able to do it yourself.
