UK decision boundary

At the same price, capacity you need and friction you can avoid decide the transaction.

Neither mower gets a discount advantage. Compare actual lawn fit, setup, terrain handling, software, support and the evidence gaps that matter to your garden.

Market discipline: This page is for UK buyers. It uses GBP, UK price sources and a dated snapshot. A German, Finnish or US price can produce a different decision.

How a UK buyer should read this

1. Job fit comes before price.

Reject an option that cannot cover your lawn size, slope, access or boundary conditions. Cheap but incapable is not value.

2. The premium needs a job.

More money should buy something you use: fewer rescues, better terrain capability, lower downtime, easier setup, stronger UK support or a longer useful life.

3. Unknown is priced by consequence.

If mower downtime is tolerable and replacement is easy, a newer or less proven model can be a rational gamble. If service disruption is expensive, pay more attention to mature evidence and UK support.

4. Re-run after a sale.

Useworthy does not freeze a permanent winner. A real UK sale can flip the transaction.

Is the break-even lifespan a reliability forecast?
