Had this mower for 6 years. I'm quite hard on them and have needed to replace wheels, handlebar, height adjuster, plastic under-panel, blade holder.
The mower grass box is triangular in shape - narrow where it joins the mower and stepped in height towards back - this makes it v hard to empty when full and results in lots of shaking and backache!
Mine has a non-Briggs engine and actually, this has had two services and generally been quite reliable.
SO if you're after a mower for lighter duty, it's not too bad at all. Mine doesn't feel built to last like the older ones etc etc.
