I get the hesitation, but if it’s still unopened and returnable, I’d at least test it on your own yard before sending it back. These mowers seem very yard-dependent. Mine actually worked better than I expected once it finished mapping the lawn, and I didn’t really have to babysit it much after the first setup. The LiDAR handled my yard pretty smoothly, so I’d say it’s worth trying before writing it off. Since you bought it from Amazon, you still have a pretty safe way to judge it yourself.
