Our verdict
The bottom line
The Gardena Sileno Life sits between the Sileno Minimo and the Husqvarna 305 in capability and price. For 600–1000m² lawns it's the smart choice — quieter than Husqvarna, better-built than Worx Landroid. The Gardena Smart app is the weakest part.

Buying second-hand
Used-market tip
£350–650 used. Boundary wire walk-perimeter check as standard. Battery cells last about 4 years; demand a runtime test. Reset Gardena Smart account before purchase. Dock contacts gold-plated — Gardena uses better dock metal than most rivals.
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.
