Our verdict
The bottom line
The "I already own Ryobi" mower. If your shed has 5+ Ryobi 18V tools, this slots in beautifully. Otherwise the 18V platform is overworked here and a 40V/56V rival cuts better.

- Hundreds of compatible Ryobi tools
- Battery resale is decent
- Lightweight
Cons

Buying second-hand
Used-market tip
£100–180 used — strongly check both batteries individually. Mismatched battery pairs (one new, one tired) give 10 minutes of runtime. Insist on a real-world cut test. Ryobi ONE+ batteries are the most counterfeited — buy from a seller who can show original receipts.
Where to look: Facebook Marketplace and Gumtree are usually 20–30% cheaper than eBay UK for petrol mowers because most sellers want local pickup. eBay tends to win on cordless and electric (lighter, easier to ship). Always insist on a starting demonstration before paying.
