Our verdict
One of the few compact cordless mowers with a rear roller, so you get stripes without a petrol engine. The brushless motor and 5 year warranty are reassuring, but the supplied 2Ah battery only manages about 15 minutes, so a spare or larger pack is almost essential. Good for small striped lawns.
Pros & cons

- Rear roller gives proper stripes
- Brushless motor
- 3-in-1 collect, discharge or mulch
- 5 year warranty
Cons

Buying second-hand
Factor in a second battery as the included 2Ah is small. Check the roller turns freely and the battery charges. Around £150 to £165 used as a kit.
