## What reviewers found

### Segway Navimow X315

- Notebookcheck: Stable RTK and straight passes on two test areas. Detected a hedgehog dummy and a hose but missed a small tennis ball once in three tries. Ran about 2 hours per charge, recharged in about 1 hour, measured about 55 dB. Left at least 10 cm uncut at edges and did not reliably climb a 50% ramp. Verdict: almost perfect.

- PC-Welt: Editors' Choice. On a 120 m² lawn it set up in minutes, mowed in changing lanes and reached edges well, with rear wheels gripping on gravel. First passes left narrow uncut strips that cleared on later runs. Random obstacles were detected reliably; about 60 min to charge.

### Sunseeker X5 Gen 2

- inside digital: Mixed verdict. Edge cutting was praised and the six blade floating deck cut cleanly, but it missed a garden hose and refused to mow where network RTK signal was weak in a city garden. Its IPX5 rating was the lowest in the comparison. [Source](https://www.inside-digital.de/tests/maehroboter-sunseeker-elite-x5-gen2-testbericht-kantenschnitt)
- instalki.pl: Positive verdict after two weeks on a 337 m² flat lawn: about 122 m² per hour, about 100 minutes per charge, about 60 dB, no escapes from the map. It left about 8 cm uncut along walls versus 3 cm claimed and hit a small ball and a porcelain snail. [Source](https://www.instalki.pl/testy/hardware/robot-koszacy-sunseeker-elite-x5-gen2-recenzja/)
