This is the best lawnmower I've owned. Having suffered for years with a Qualcast cylinder electric mower I thought I'd try a rotary. It's powerful and cuts the grass cleanly without scraping the surface. The edge fins do get most of the grass against paving and walls, but some is left. But that's not too much of a problem for me.
The only drawbacks so far for me is the poorly designed grassbox. It's easy to fit and remove, but it is a bit difficult to empty sometimes. But that's only a small issue.
Overall I'd recommend it for most small to medium sized lawns.
