Our verdict
A perfectly fine first cordless for a small lawn at a genuine bargain price. Webb is a long-established UK brand even if today's products are mostly imported. The 36V battery is a sticking point — useless for anything else, no resale value.

- Mulch plug standard
- Light at 13kg

Buying second-hand
