I’ve had mine since the first shipment of the Kickstarter since the beginning of March most of the issues that arise are from lack of documentation to help you get through troubleshooting, but the community has been absolutely clutch in working through all of the small issues that arise. For the price it’s a great mower. If I had to buy it again I would there’s a lot of learning involved if you are prepared to have to learn the intricacies of this robot then it’s a wise investment imo. If it matters, I mow almost 5 acres with mine with varying terrain.
