Our verdict
Segway took longer than Husqvarna to get the basics right but the H800E is solid. Reliable and well-supported now. The 18cm cut is the only limitation — it is slow.

- Segway support is improving in UK

Buying second-hand
£1000–1700 used. VisionFence base must be included with calibration intact. Test it in mixed lighting if possible — heavy rain can fool the cameras. Segway accounts transfer cleanly if seller does the factory reset; insist on this.
