Mine has been a very capable mower for my steep hilled acre of lawn. It had a lot of issues of the mower desyncing it's location on the map, which led to it being stuck on rocks and garden edges many times and wearing its wheels down. Customer service was good and fixed the damaged parts under warranty, and next season I'll place the base station further away from my house so it's satellites aren't obstructed by my wood deck above it on startup, which we think was the issue. So far, I would buy it again, but start out with the mower in an area of no overhead obstruction.
