## What reviewers found

### Segway Navimow X330

- TechRadar: Tested the X350, a larger battery sibling in the same X3 series. It mowed fast and stayed accurate under trees, but missed a very small ball and may struggle on rough terrain with 2WD.

### Segway Navimow X450

- PCWorld (TechHive): Testing the X430 sibling, it climbed an uneven, sloped yard without spinning, sliding or stalling, stayed inside the boundary around trees and a play set, and did not slip over a raised edge where the i215 had. Editors' Choice; cons were price, size and weight. [Source](https://www.pcworld.com/article/3192029/segway-navimow-x430-review.html)
- Expert Reviews: Testing the X4 series (X430 unit), it praised grip on 40° slopes, gravel and kerbs and easy setup. The first pass was very good, the second excellent, and it stayed 5 to 10 cm from beds. It ran about 150 min per charge and measured 68 dBA.
