## What reviewers found

### Segway Navimow X350

- PCWorld (TechHive): On a challenging, sloped yard it navigated well day and night and cut as well or better than the i and H series. AI mapping failed on the slope and the front end slid downhill when driving across a slope. Setup took about 30 minutes; recharges took 60 to 90 minutes.

- TechRadar: On a 1,000 m² (0.25 acre) lawn with large trees it mowed fast and neat, stayed accurate under trees and respected no mow zones. It avoided a ride on toy and a soccer ball but ran over a tangerine sized ball. Sub scores: design 5/5, performance 4.5/5, app 5/5, value 4/5.

### Sunseeker X7 Gen 2

- Yanko Design: One week on a 6,777 sq ft Texas lawn with 32 oaks and an embankment. RTK fixed within a couple of minutes, the map held all week, it cut damp St. Augustine evenly, avoided a hose at night and fit through a 28 in gap.

- Homecrux: Hands on with five Sunseeker mowers sent by the company. The X7 ran at night, avoided obstacles reliably and left minimal missed spots; the article calls it the X7 Plus Gen 2 in one place and gives no measurements.
