Boundaries are always off, sometimes by a couple inches, sometimes over 12 inches even with a good RTK signal. Editing boundaries doesn't seem to change anything. I have a new lawn, no mature trees, RTK in a perfectly clear location as far from the house as it can be. It also randomly loses it's brains and just wanders around doing nothing.
X7 arrived the next day for me. Setup was straight forward. Setting the mowing zones with no go areas etc. was simple and quick. When it started mowing I anticipated their might be issues but the mower handled all the areas and trees that I did not mark fine. It has completed numerous complete mowings and required no assistance. Everyone in the neighborhood slows down to watch it working. I would definitely recommend the Sunseeker to everyone.
Mows well but has a lot of errors and mechanical issues. Support has been mixed. The app is confusing but does decent enough once you know how to use it. It does throw a lot of errors regarding the bumper and RTK initializing. The mower does a good job for the most part though
